Modify User Accounts

Unless you define a user name or UID number that conflicts with an existing one, you should never need to modify a user account's login name or UID number. Use the following steps if two user accounts have duplicate user names or UID numbers:

• If two user accounts have duplicate UID numbers, use Admintool to remove one account and re-add it with a different UID number. You cannot use Admintool to modify a UID number of an existing user account.

• If two user account have duplicate user names, use Admintool to modify one of the accounts and change the user name.

  If you do use Admintool to change a user name, the home directory's ownership is changed (if a home directory exists for the user).

One part of a user account that you can change is a user's group memberships. Admintool Modify option lets you add or delete a user's secondary groups. Alternatively, you can use the Groups window to directly modify a group's member list.

You can also modify the following parts of a user account:

• Comment

• Login shell

• Passwords

• Home directory

• AutoHome setup

• Credential table setup

• Mail server
