Setting Permissions

As a shared mailbox administrator, you will be setting permissions for all the users of the box. Before following the procedures on this page you may want to review the definitions, list of available permissions, examples of how they might be combined and the commands you can use.

Adding a user to a shared mailbox or modifying the permissions of an existing user

1. Under Solaris or a capable e-mail client, at the Unity prompt, type:

   add cyrus

2. Type:

   cyradm shared.mail.ncsu.edu

3. Enter your Unity ID and password when prompted. You are now logged in.
4. To see the current Access Control List (ACL) for the shared mailbox, type:

   lam sharedbox

   where sharedbox is the name of your box.

5. You will see a listing of the Unity IDs of the users of the box and the combination of permissions granted to each, similar to the following example:
   
   

   uni10map.unity.ncsu.edu> lam sharedbox
   anyone p
   sarah lrswipda
   twk lrswipda
   gierka lrswipda
   hmn lrswipda
   ershanno lrswipda
   chking lrswipda
   cyrus d
   
   uni10map.unity.ncsu.edu>

   
   NOTE: The user "anyone" with permission "p" (Post) should always remain in this ACL. Otherwise, no one (including the users on the ACL) will be able to send mail to the box unless they have specific Post permission.

6. Use the sam command to add a user or modify existing permissions. Type:

   sam box userid permissions

   where box is the name of the shared mailbox
   userid is the Unity ID of the user being added or whose permissions are being changed
   permissions is the combination of permissions being given to that user

   For example, if you added a new user bubba with Look and Read permissions (lr), and then used the lam command as in Step 4 above, the list above would now look like this, with the new user appearing as the last item:
   
   

   uni10map.unity.ncsu.edu> lam sharedbox
   anyone p
   sarah lrswipda
   twk lrswipda
   gierka lrswipda
   hmn lrswipda
   ershanno lrswipda
   chking lrswipda
   cyrus d
   bubba lr
   
   uni10map.unity.ncsu.edu> 
   

Removing a user from a shared mailbox

To remove a user from the box you will need to remove all of that user's permissions. For example, to remove bubba from the list above, you would use the sam command as in Step 6 and set the permissions to "none" as follows:

uni10map.unity.ncsu.edu> sam sharedbox bubba none

You can use the lam command as in Step 4 to verify that the user has been removed from the ACL:

uni10map.unity.ncsu.edu> lam sharedbox
  anyone p
  sarah lrswipda
  twk lrswipda
  gierka lrswipda
  hmn lrswipda
  ershanno lrswipda
  chking lrswipda
  cyrus d
