Users
Manage user entries. All users are POSIX users.
IPA supports a wide range of username formats, but you need to be aware of any
restrictions that may apply to your particular environment. For example,
usernames that start with a digit or usernames that exceed a certain length
may cause problems for some UNIX systems.
Use 'ipa config-mod' to change the username format allowed by IPA tools.
Disabling a user account prevents that user from obtaining new Kerberos
credentials. It does not invalidate any credentials that have already
been issued.
Password management is not a part of this module. For more information
about this topic please see: ipa help passwd
EXAMPLES:
Add a new user:
ipa user-add --first=Tim --last=User --password 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
