"""
Users

Manage user entries. All users are POSIX users.

Disabling a user account prevents that user from obtaining new Kerberos
credentials. It does not invalidate any credentials that have already
been issued.

EXAMPLES:

 Add a new user:
   ipa user-add --first=Tim --last=User --passwd tuser1

 Find all users whose entries include the string "Tim":
   ipa user-find Tim

 Find all users with "Tim" as the first name:
   ipa user-find --first=Tim

 Disable a user account:
   ipa user-disable tuser1

 Enable a user account:
   ipa user-enable tuser1

 Delete a user:
   ipa user-del tuser1
