What does Documentum recommend about deleting users?

October 28, 2010

Every SysObject or SysObject subtype in the Docbase has an attribute called owner_name that identifies the user who owns the object. Its better to  deactivate the  users, rather than deleting them based on the following issues:

  1. Before deleting a user from a Docbase, you must update the objects created by the deleted user to change the owner_name to identify a different user. You do not need to change the owner_name if you deactivate the user.
  2. When you delete a user, the server does not remove the user’s name from objects in the Docbase such as groups and ACLs. It is possible to delete a user, and then re-create the user with the same name. However, if you add a new user with the same name as a previously deleted Docbase user, the new user will inherit the group membership and object permissions of the previously deleted user.
  3. You cannot delete the Docbase owner, installation owner, or yourself.
  4. When you no longer need a user account, deactivate the user. Deactivating a user is better than deleting a user. Once a user is deactivated in a Docbase, that user will not be able to log in to that Docbase. You must have Sysadmin or Superuser privileges to deactivate or reactivate a user.
  5. You cannot change the login state of the Docbase owner, installation owner, or yourself. You deactivate and reactivate users by changing the user’s login state using Documentum Administrator, DQL or the API.
  6. By default, users are active when you create them, so you do not need to activate new users. The user’s login state is tracked by the user_state attribute of the dm_user object. If you deactivate a user who is currently logged in, the change takes affect when the user next logs in.
  7. If necessary, a user with Superuser privileges can use a ticket to log in as a deactivated user, and a user with Superuser privileges can add a deactivated user to a group.

Feel free to add/correct points. Appreciate your comments.
