Managing Groups that You Own in the U-M Online Directory

S4277 • February 2008

This document contains instructions for creating, modifying, and managing e-mail groups in the U-M Online Directory. Note that only members of the U-M community who have their own directory entries can create groups in the directory.

Table of Contents


What Is a Directory Group?

A group entry in the directory is basically a list of people and/or groups. These are used primarily for sending e-mail. Mail sent to a group created in the directory is delivered to each member of the group. Groups created in the directory can be used by anyone to send mail, regardless of what e-mail package they use. To send e-mail to a directory group, send it to groupname@umich.edu (where you have substituted the actual group name for groupname).

Directory groups are also sometimes used for authorization; some groups control access to web sites, wikis, and other online resources.

Responsibilities of Group Owners

  • Have a clear purpose for the group. It is helpful to state this purpose in the description part of the group entry.
  • Include group members only with their permission. Include groups as members only with the permission of the group owner(s). Owners of groups used for University business (for example, a list of staff members in a particular department), however, may be required by their unit to include people.
  • Remove group members who ask to be removed. Owners of groups used for University business, however, may be required by their unit not to remove people from those groups.
  • Provide a valid mail-forwarding address in your individual directory entry. This allows group members to contact you with requests and allows directory administration to send you reminders to renew your group before it expires.
  • Renew your group on a yearly basis if you wish it to remain active. Groups expire after one year unless they are renewed. You may renew your group as often as you wish.
  • Consider setting more than one owner for your group. This is particularly important if you will be away for any length of time and will need to have others maintain the group in your absence. It is strongly recommended that groups used for University business have more than one owner.
  • Delete your group from the directory when it is no longer needed.
  • If you leave the University, either delete your group(s) or designate a new owner.
  • Set your group appropriately to meet the members' needs and reduce unwanted mail. For example, if the group is for discussion among group members only, set it to be members-only; that way, no one else will be able to send mail to the group.
  • Do not use the group for sending spam. It is a violation of University policies to create an e-mail group with the intent of sending out what would generally be regarded as spam (unless the group owner received permission from the members of the group). Advertisements or solicitations for commercial events or endeavors are strictly prohibited.

If you have questions about appropriate use of groups, contact the IT User Advocate by sending e-mail to itua@umich.edu.

ITCS reserves the right to immediately disable any directory group that is being used inappropriately and has generated complaints from group members.

Creating a Group

  1. Go to the directory (http://directory.umich.edu).
  2. Click the Bind button and log in with your uniqname and UMICH Kerberos password. (Before you can make changes to the directory, you must "bind" to the directory as yourself.)

    Screen shot of Bind button.

  3. Click the Add button.

    Screen shot of Add button

  4. In the text box underneath the words "Please enter the name of the group to create," type the name you want your group to have. Do not include "@umich.edu" as part of the name. (See Appendix A: Naming Your Group later in this document for information about naming e-mail groups. For example, you should use spaces rather than periods to separate words.)

    Screen shot of box where you enter the name for your group

  5. Click the add entry button to create the group.

    Screen shot of add entry button

  6. IMPORTANT! Directory groups must be renewed on a yearly basis. Groups that are not renewed will expire. See Renewing Groups below for instructions.

  7. You will see confirmation that your group has been created. You can now customize your group by adding additional owners, members, and more. See Appendix B: Parts of a Group Entry for details about the changes you can make to your group entry. Be sure to click the Save Changes button if you make changes.

    Screen shot of customizing your new group

  8. When you are finished using the directory, click the Unbind button (at the top of the page), click logout (in the bottom right corner of the page), and quit or exit your web browser.

Making Changes to a Group

NOTE: Only the owner of a group can make changes to that group.

  1. Go to the directory (http://directory.umich.edu).
  2. Click the Bind button and log in with your uniqname and UMICH Kerberos password.
  3. In the Search text box at the upper left corner of your window, enter the name of the group you want to modify, then click the Search button.

    Screen shot of Search box and button.

  4. The directory entry for your group will be displayed. Click the Modify button.

    Screen shot of Modify button.

  5. Make your changes, by typing text in the appropriate boxes or clicking radio buttons where indicated, then click the Save Changes button.

    For an explanation of each part of a directory group entry, see Appendix B: Parts of a Group Entry later in this document.

    Screen shot of Save Changes button.

  6. When you are finished using the directory, click the Unbind button (at the top of the page). Click the logout link (in the lower right corner of the window) when you are finished using U-M web-authenticated applications.

Finding All the Groups You Own

  1. Go to the directory (http://directory.umich.edu).
  2. Click the Bind button and log in with your uniqname and UMICH Kerberos password.
  3. Click your uniqname to display your entry.

    Screen shot of where to click your uniqname -- in the upper right corner of the window.

  4. Near the upper left corner of your directory entry, click the Show Ownership button.

    Screen shot of Show Ownership button.

  5. In the list of groups you own, you can

    • Click a group name to see that group's entry.
    • Click the Delete or Renew button next to a group's name to delete or renew it. Then click the Save Changes button (near the top left of the window).

    Screen shot of list of owned groups.

  6. When you are finished using the directory, click the Unbind button (at the top of the page). Click the logout link (in the lower right corner of the window) when you are finished using U-M web-authenticated applications.

Deleting Groups

Only the owner of a group can delete that group from the directory. If you are going to delete a group and think you might need a copy of the group for future reference, you can create a back-up copy in your IFS home directory. (See Appendix D: Saving and Restoring an E-Mail Group Using Your IFS Home Directory for details.)

TIP: If a group has multiple owners, please check with the other owners before deleting it.

To Delete a Single Group
  1. Go to the directory (http://directory.umich.edu/).
  2. Click the Bind button and log in with your uniqname and UMICH Kerberos password. (Before you can make changes to the directory, you must "bind" to the directory as yourself.)
  3. In the Search text box at the upper left corner of your window, enter the name of the group you want to modify, then click the Search button.
  4. The directory entry for your group will be displayed. Click the Delete button.

    Screen shot of list of Delete button.

  5. At the Verify Changes screen, click the Yes, Delete button.
  6. When you are finished using the directory, click the Unbind button (at the top of the page). Click the logout link (in the lower right corner of the window) when you are finished using U-M web-authenticated applications.
To Delete Multiple Groups
  1. Go to the directory (http://directory.umich.edu/).
  2. Search for your own entry.
  3. Click the Bind button and log in with your uniqname and UMICH Kerberos password.
  4. Click the Show Ownership button.

    Screen shot of Show Ownership button.

  5. Check the Delete radio button to the left of each group that you want to delete. Then click the Save Changes button.

    TIPS:

    If you see a list of groups without buttons, it is because you are not bound to the directory. Click the Bind button and log in, then click Show Ownership.

    If you don't recognize a group name, click it to see the group's entry before you delete the group. Some groups have multiple "also known as" names, but only the original name will appear in your list of owned groups. You may know the group under one of its "also known as" names.

    You can renew groups you want to keep at the same time you delete your obsolete groups. Click the Renew button next to those groups.

    Screen shot of deleting multiple groups.

  6. At the Verify Changes screen, click the Yes, Change button.
  7. When you are finished using the directory, click the Unbind button (at the top of the page). Click the logout link (in the lower right corner of the window) when you are finished using U-M web-authenticated applications.

Renewing Groups

IMPORTANT! You must be an owner of a group to renew it.
To Renew a Single Group
  1. Go to the directory (http://directory.umich.edu/).
  2. Click the Bind button and log in with your uniqname and UMICH Kerberos password.
  3. In the Search text box at the upper left corner of your window, enter the name of the group you want to renew, then click the Search button.
  4. The directory entry for your group will be displayed. Click the Renew button near the upper left corner of the entry.

    Screen shot of Renew button.

  5. You will see confirmation that your group has been renewed for one year.

    NOTE: Expiration dates are updated once a day, so the actual expiration date for the renewed group will not change until sometime the next day.

    Screen shot of renewal confirmation.

  6. When you are finished using the directory, click the Unbind button (at the top of the page). Click the logout link (in the lower right corner of the window) when you are finished using U-M web-authenticated applications.

  3. Click the Bind button and log in with your uniqname and password.
  4. Click the Show Ownership button.

    Screen shot of Show Ownership button.

  5. Check the Renew radio button to the left of each group that you want to renew, the click the Save Changes button.

    Screen shot of Show Ownership button.

    NOTE: If you see a list of groups without buttons, it is because you are not bound to the directory. Click the Bind button and log in, then click Show Ownership.

    HINT: You can delete your obsolete groups at the same time. Click the Delete button next to each group that you want to delete.

  6. On the Verify Changes page, click Yes, Change.
  7. You will see confirmation that your groups have been renewed.

    NOTE: Expiration dates are updated once a day, so the actual expiration date for the group will not change until sometime the next day.

  8. When you are finished using the directory, click the Unbind button (at the top of the page). Click the logout link (in the lower right corner of the window) when you are finished using U-M web-authenticated applications.

Disabled Groups

Directory groups expire after one year unless they are renewed. When a group expires, it becomes disabled. At that point, all group functions stop working except the ability to find the group when searching the directory. Mail sent to the group will be returned to the sender as undeliverable; the error message will say that the group does not exist. If the group is used for authorization (for example, to allow access to a restricted web page), the authorization will fail.

The group owner(s), 4-HELP, the ITCS Accounts Office, Directory Administration, and the IT User Advocate can renew disabled groups.

You renew a disabled group the same way you renew any group that you own—by clicking a Renew button. (See renewal instructions earlier in this document.)

This is what a disabled group looks like in the directory:

Screen shot of disabled group entry.

NOTE: Directory groups are sometimes disabled in response to complaints from group members when use of the group violates University policy. Owners are not able to renew groups that are disabled for policy violation.

Frequently Asked Questions

  1. Can I hide the membership of my group?
    Yes. You can do that by making the group private. See Appendix D: Private Groups for instructions.
  2. Can I set my group up so that only the group members—and no one else—can send mail to it?
    Yes. You can do that by making the group members-only. See Appendix E: Members-Only Groups for instructions. If anyone other than a group member sends a message to the group, the message will be returned to the sender as undeliverable.

    CAUTION! If your members-only group is itself a member of another group, you will need to permit that group to send mail to your members-only group. See Appendix F: Permitted Groups for Members-Only Groups for instructions.

  3. Can I list more than one owner for my group?
    Yes! In fact, we recommend that you have more than one owner. This is especially important for groups that are used for University business. That way owners can share the group management tasks and cover for each other when one is away on vacation or for some other reason.
  4. How do I protect my group from spam?
    There are several things you can do to reduce spam sent to your group:

    • Make sure the Do Not Spam List is turned on for your group. The Do Not Spam List rejects mail sent to your group from known spammers. See Using the Do Not Spam List to Reduce Spam (S4323) for details.
    • Do not list your group's address on web pages.
    • If no one but your group members will need to send mail to the group, set it to be members-only. Then no one else will be able to send mail to it. (See Appendix E: Members-Only Groups for instructions.)
  5. I have a lot of groups. Can I renew them all at once?
    Yes, you can. Follow the renewal instructions for multiple groups earlier in this document.
  6. Will I be notified before my group expires?
    Yes. Group owners receive a renewal reminder through e-mail 90 days before a group is set to expire and another 30 days before expiry. The reminders are sent to the e-mail forwarding address listed in the group owner's directory entry, so be sure you have your current e-mail forwarding address listed.
  7. Will I be notified after my group expires?
    No. The final notice you will receive about a group is 30 days before it is to expire.
  8. What happens to my group if it expires?
    When your group expires, it is disabled. That means it stops working, and mail cannot be sent to it. It remains in the directory in a disabled state for one year. During that time, you can still renew it. After it has been disabled for one year, it is deleted from the directory. Once it is deleted, it cannot be renewed. For details about group expiry, see Directory Group Expiry Policy (R1455).
  9. What happens if someone sends mail to a disabled group?
    Mail sent directly to a disabled group will be returned to the sender as undeliverable. The error message will state that the group does not exist.
  10. What happens if someone sends mail to a group that contains a disabled group?
    Mail sent to a group that contains a disabled group will not be delivered to the members of the disabled group. No error message will be generated, however, so the sender will not be notified that some people did not receive the message.
  11. Can I set my group to be both moderated and members-only?
    Yes, but we recommend against it unless you have a moderator who is willing to pay a lot of attention to mail sent to the group. The members-only feature takes precedence over the moderation feature. Here's how mail delivery works for a members-only, moderated group:

    • If a member of the group sends mail to the group, the message is delivered to all group members.
    • If a non-member sends mail to the group, the message is delivered to the moderator only. The moderator must then look at each piece of mail sent to the group to determine if it was sent by a group member or not. If it was not sent by a group member, the moderator must then decide whether to send the mail on to the group.

Appendix A: Naming Your Group

Length. An e-mail group in the U-M Online Directory can have a name up to 64 characters long, including spaces.

To avoid confusion with uniqnames, group names must be longer than eight characters or include at least two words separated by a space. It's important to avoid confusion with uniqnames because people take precedence over groups in e-mail delivery; if a group name and a uniqname are the same, mail sent to that name will go to the individual rather than to the group—regardless of which was created first in the directory.

To separate words, use spaces. Most punctuation marks cannot be used when creating names in the directory. This is because punctuation marks in entry names may cause confusion with different mail systems. For example, most e-mail programs automatically replace spaces with "dots" or periods ( . ); therefore, you cannot use periods as part of your group name (use spaces instead).

Don't use uniqnames. Group names should not be the same as a potential or existing uniqname. In other words, group names should never consist of 3-8 alphabetic characters. For example, if a group chooses to name itself "bjensen" and a person is already using "bjensen" as his or her uniqname—or even if someone chooses that uniqname after the directory group is named—mail sent to bjensen@umich.edu will be delivered to the person, rather than the group.

Person entries have precedence over group entries for e-mail delivery. This means that if you create a group with a name that an individual later takes as his/her uniqname, mail sent to that name will be delivered to the person rather than the group, without notification to the group or the group owners.

Don't use people's names. Giving a group a name such as "Michael Jordan" could cause a conflict with an individual entry in the directory.

Be descriptive and easy to remember. Group names in the U-M Online Directory should be descriptive and easy to remember. Please resist the urge to be cute, and do be sensitive to names that might be offensive to others. In addition, try to avoid names that are too generic. For example, a name such as "Admin" is not very descriptive or helpful; instead, a name such as "UMCE Linux Server Administrators" might be a better choice.

Appendix B: Parts of a Group Entry

You may or may not see all these parts when you view group entry. If a field is empty (for example, if no fax phone number has been entered), that part of the entry may not appear. All parts are visible when you are modifying a group.
  • Also Known As (Aliases): In this field, enter additional names that you would like people to be able to use when sending mail to your group. For example, if your group is named "University of Michigan Test Group," you might also want mail sent to U-MTestGroup@umich.edu to go to your group members. Therefore, you would enter "U-MTestGroup" (without the quote marks) in the Also Known As field. Enter aliases sparingly to avoid potential with other groups that might have the same alias. It is often better to have people create their own shortcuts in their own e-mail address books rather than using the directory to create them.
  • Notice: You may enter any text you wish in this field. It will show up as a notice in the group's directory entry. For example, you might enter text notifying people how to join the group or notifying them that the group will not be used much during the summer.
  • Description: You may enter a description for your group in this field. For example, you might explain the purpose of your e-mail group and specify what kind of messages are considered appropriate. It is especially important to include a description if the group is used for University business.
  • Phone Number: If there is a phone number for your group, you can enter it in this field.*
  • Fax Number: If there is a fax number for your group, you can enter it in this field.*
  • * Use this format for phone numbers:
    +1 555 555 5555
    The +1 is the code for the USA, which is followed by the area code, then the seven-digit phone number.

  • Postal Address: If there is a postal address for your group, you can enter it in this field.
  • More Info (URL and Label): If your group has a web page, you can enter the web address—or URL—in the URL field. Then people can click the URL in your group's directory entry to go to that web page. If you would like people to be able to click on the name of your group's page rather than on a URL, enter a name in the Label field.
  • See Also: You can list related e-mail groups or individuals in your group's directory entry by entering their names or uniqnames, one per line, in this field.
  • University Members: In this field, list the members of your group by uniqname or full name. Do not enter e-mail addresses. Only people who are listed in the U-M Online Directory can be listed in this field. Note that both individuals and groups can be listed. If you want someone who is not in the directory to be a member of your group, use the Non-University Members field (see description of the Non-University Members field below).
  • Non-University Members: Use this field to add group members who are not listed in the U-M Online Directory (for example, people at other universities or who use commercial e-mail products such as AOL). Enter full e-mail addresses (individual people or groups), one address per line. Full addresses with names can also be used. (For example, the format of "John Doe <john.doe@example.com>" will work; the "John Doe" part is considered a comment, and the "<john.doe@example.com>" is the full address. If you use this format, the angle brackets must be included around the actual address.)
  • Requests To: It is an Internet standard for people to be able to send mail to the administrator of an e-mail group by sending e-mail to groupname-request, where the group's name is substituted for groupname and the full e-mail address is used. In the Requests To field, list the person(s), by full name or uniqname (do not enter e-mail addresses), who should receive these messages. For example, if your group's address is TestGroup@umich.edu, the mail would be sent to TestGroup-request@umich.edu.
    NOTE: Persons listed in the Requests To field must be members of the U-M community—that is, they must have an entry in the U-M Online Directory. If you want someone who is not in the directory to receive the request messages, use the E-Mail Requests To field (see description of the E-Mail Requests To field).
  • E-Mail Requests To: If you would like someone who is not listed in the U-M Online Directory to receive messages sent to groupname-request@umich.edu (where the group's name is substituted for groupname), enter their full e-mail address here. (See Requests To description above for details.)
  • Errors To: In this field, you can list someone (or several people) to receive error messages concerning mail sent to the group. (Enter full names or uniqnames; do not enter e-mail addresses.) For example, if mail sent to someone in the group bounces, the message reporting the bounced mail will be sent to the person(s) listed in the Errors To field. It is best to list one or more of the group owners, because only the group owner(s) can make any needed changes to the group in response to receiving the error messages.
    NOTE: If both the Errors To and E-Mail Errors To fields are left empty, the errors will be sent to all group owners.
    NOTE: Persons listed in the Errors To field must be members of the U-M community—that is, they must have an entry in the U-M Online Directory. If you want someone who is not in the directory to receive the error messages, use the E-Mail Errors To field (see description of E-Mail Errors To field).
  • E-Mail Errors To: If you would like someone who is not listed in the U-M Online Directory to receive error messages (see Errors To description above for details), enter their full e-mail address here.
  • Owner: The person who creates a group is automatically listed as its owner. You can add owners by entering their uniqnames or full names (do not enter an e-mail address or a group name) in this field. Enter only one person per line. A group's owners are the only ones who can make changes to the group. If the group owner will be leaving the University, it is important for him or her to add a new owner who can then make changes as needed. Please note that only people can own groups. Groups cannot own groups, because no one can then bind to the directory as the group to make changes to it.
  • Others May Join: You can allow other people to join your e-mail group if you wish. Click the True radio button to allow people to join. People can then find the group's directory entry and join by themselves without having to ask the group's owner(s) to add them. They can also remove themselves later if need be.
  • Private Group: The list of group members can be hidden from public view by making a group private. Click the True radio button to make the group private. Only the owner and members can see the list of members, and they must bind to do so. Only the group owner can make a group private. Note that making a group private does not prevent non-members from sending e-mail to the group. See Appendix D: Private E-Mail Groups for details.
  • Members-Only Group: You can set your group up so that only the members of the group can send mail to it by making it a members-only group. Click the True radio button to make your group a members-only group. See Appendix E: Members-Only Groups for details.
  • Permitted Groups for Members-Only Group: The permitted groups feature applies only to a group designated as members-only that is itself a member of another group. Using this feature allows mail sent to the permitted group to reach the members-only group. See Appendix F: Permitted Groups for Members-Only Groups for details.
  • Use Do Not Spam List: When this is set to True, mail sent to your group from known spammers is rejected. See Using the Do Not Spam List to Reduce Spam (S4323) for details.
  • Moderator's E-Mail Address: If you want your group to be moderated, enter the moderator's full e-mail address in the Moderator's E-Mail Address field. You can have more than one moderator for your group by entering additional e-mail addresses, one per line. See Appendix C: Moderated E-Mail Groups for details.
  • Suppress 'No E-Mail Address' Errors: If the True radio button is selected, then "no e-mail address" errors will be supressed. That is, if mail is sent to the group and one or more University group members do not have mail forwarding addresses in their entries (which means they would not receive the mail sent to the group), the person(s) listed in the Errors To fields will not receive an error message alerting them to that fact. If the False radio button is selected, or if no button is selected, then error messages will be sent in the above situation.

Appendix C: Moderated Groups

The U-M Online Directory allows e-mail groups to be designated as "moderated groups." This is one way to prevent inappropriate messages from being sent to a group.

In a moderated group, messages sent to the group are received by the moderator, a person who takes responsibility for screening the messages. The moderator decides whether the message is appropriate and, if it is, forwards it on to the group. Only the moderator(s) can send e-mail directly to a moderated group.

WARNING! The moderator will not receive notification that messages are not going to the group. The moderator must remember that any mail he or she receives that is addressed to the group has only been delivered to the moderator. This means that the moderator must be careful to review the To line of all received messages. The group will not receive any messages that are sent to the group unless the moderator sends them on.

NOTE: If a group is both moderated and members-only (see Appendix E: Members-Only Groups), e-mail sent to the group by a group member will be delivered to all the members and will not stop at the moderator. If e-mail is sent to the group from someone who is not a group member, the mail will stop at the moderator(s), who can then decide whether or not to forward the message to the rest of the group.

The group owner can serve as moderator or can designate one or more moderators. Be sure to get a group member's permission before designating him or her as moderator. If the group has more than one moderator, each of them will receive copies of the messages that are addressed to the group. The moderators will have to agree on how they will handle the incoming messages and who will be responsible for forwarding them to the rest of the group.

  1. Connect to the directory (http://directory.umich.edu).
  2. Click the Bind button and log in with your uniqname and UMICH Kerberos password.
  3. Locate the group that you want to make moderated by using either the Search box or the Show Ownership buton.
  4. With the selected group displayed, click the Modify button.
  5. Scroll down, near the bottom of the entry, to the Moderator's E-Mail Address heading.
  6. In the Moderator's E-Mail Address box, enter the moderator's full e-mail address (for example, bjensen@umich.edu). You can have more than one moderator. Only the moderator(s) will be able to send e-mail to the group members.
  7. Scroll down to the very bottom of the entry, and click the Save Changes button.
  8. When you are finished using the directory, click the Unbind button (at the top of the page), click logout (in the bottom right corner of the page), and quit or exit your web browser.

Appendix D: Private Groups

The list of group members can be hidden from public view by making a group private. Only the owner and members can see the list of members, and they must bind to do so. Only the group owner can make a group private. Note that making a group private does not prevent non-members from sending e-mail to the group.

  1. Connect to the directory (http://directory.umich.edu).
  2. Click the Bind button and log in with your uniqname and UMICH Kerberos password.
  3. Locate the group that you want to make private by using either the Search box or the Show Ownership button.
  4. With the selected group displayed, click the Modify button.
  5. Scroll down, near the bottom of the entry, to the Private Group heading.
  6. Under the Private Group heading, click the True radio button.
  7. Scroll down to the very bottom of the entry, and click the Save Changes button.
  8. When you are finished using the directory, click the Unbind button (at the top of the page), click logout (in the bottom right corner of the page), and quit or exit your web browser.

Appendix E: Members-Only Groups

You can set your group up so that only the members of the group can send mail to it by making it a members-only group. This is an effective way of preventing spam from being delivered to the group. If anyone other than a group members tries to send mail to the group, the mail will not be delivered to the group members.

NOTE 1: If a group is both moderated (see Appendix C: Moderated E-Mail Groups) and members-only, e-mail sent to the group by a group member will be delivered to all the members and will not stop at the moderator. If e-mail is sent to the group from someone who is not a group member, the mail will stop at the moderator(s), who can then decide whether or not to forward the message to the rest of the group.

NOTE 2: If your members-only group is a member of another group, see Appendix F: Permitted Groups for Members-Only Group for important information to help you ensure mail is delivered as expected.

To make your group a members-only group, follow these instructions:

  1. Connect to the directory (http://directory.umich.edu).
  2. Click the Bind button and log in with your uniqname and UMICH Kerberos password.
  3. Locate the group you want to make members-only by using either the Search box or the Show Ownership button.
  4. With the selected group displayed, click the Modify button.
  5. Scroll down, near the bottom of the entry, to the Members Only Group heading.
  6. Under the Members Only Group heading, click the True radio button.

    TIP: If your members-only group is itself a member of a larger group, you will need to list that larger group as "permitted" in your group's entry. Doing so permits the larger group to pass mail on to your members-only group. (See Appendix F: Permitted Groups for Members Only Groups for details.)

  7. Scroll down to the very bottom of the entry, and click the Save Changes button.
  8. When you are finished using the directory, click the Unbind button (at the top of the page), click logout (in the bottom right corner of the page), and quit or exit your web browser.

Appendix F: Permitted Groups for Members-Only Groups

The Permitted Groups feature applies only to a group designated as members-only that is itself a member of another group. Using this feature allows mail sent to the permitted group to reach the members-only group.

Here is an example of how this works:

mybuilding is a group with two members:

  1. floor1 (a group)
  2. floor2 (a members-only group)

E-mail sent to mybuilding by someone who is not a member of floor2 will be delivered to floor1, but will not be delivered to floor2.

E-mail sent to mybuilding by someone who is not a member of floor2 will only reach the members-only group floor2 if mybuilding has been listed in the Permitted Groups field of floor2. Mail must be permitted to come through mybuilding to floor2.

IMPORTANT! Permitting a group only permits the group, as an entity, to pass on mail. It does not permit the individual members of that group (mybuilding in the example above) to send mail directly to the members-only group. In the example above, mail sent to the mybuilding group is permitted to be passed on to the floor2 group. However, mail sent by a member of mybuilding directly to the floor2 group will not be delivered unless the sender is also a member of floor2.

CAUTION! If these groups are members-only in order to avoid spam, in this example any spam sent to mybuilding would be delivered to floor1 and floor2. It would then be wise to make mybuilding also a moderated group—as long as the moderator is willing to monitor all mail sent to the group and pass it on to the group members.

Appendix G: Saving and Restoring a Group Using Your IFS Home Directory

Once you make changes to an e-mail group or delete the group from the U-M Online Directory, you cannot restore the original group or its membership list. Therefore, if there's a chance you'll want to restore a group or its membership list, it's a good idea to make a back-up copy of that information. Because you cannot save a back-up of your group within the directory itself, there is a program on the Login Service that will let you save a copy of the e-mail group to your IFS home directory and then later restore it.

Saving a Group in IFS

  1. Use a secure terminal connection program to connect to the Login Service (the machine address is login.itd.umich.edu). On its Blue Disc web site, ITCS provides SSH Secure Shell for Windows and a shortcut to the Terminal program. Use either SSH or Terminal to connect to the Login Service.
  2. Log in by entering your uniqname and UMICH password when prompted to do so.
  3. At the Login Service prompt (%), type savegroup (all lowercase letters) followed by the name of the group you want to save. You may include spaces as part of the group name (for example: savegroup network users group).

    A file with the name you typed will be created in your IFS home directory; this file will contain all the membership lists and other information from your e-mail group directory entry.

  4. To verify that the group has been copied to your IFS home directory, type ls (all lowercase) at the Login Service prompt (%). Your saved group will appear in the list of files on your home directory.

  5. At the Login Service prompt (%), type logout, and then quit or exit your terminal connection program.

Restoring a Group from IFS

  1. Use a secure terminal connection program to connect to the Login Service.
  2. Log in by entering your uniqname and UMICH password when prompted to do so.
  3. At the Login Service prompt (%), type restoregroup (all lowercase letters) followed by the name of the group you want to restore (for example: restoregroup network users group).
  4. At the Login Service prompt (%), type logout, and then quit or exit your terminal connection program.

You can now send e-mail to your restored group. You can also use the U-M Online Directory to display and modify your restored group.
