Manage the IPA configuration
Manage the default values tha IPA uses and some of its tuning parameters.
To show the current configuration:
ipa config-show
To modify the configuration:
ipa config-mod --maxusername=99
The available options are:
User management options:
--maxusername=INT Max username length when creating/modifing a user
--homedirectory=STR Default location of home directories (default /home)
--defaultshell=STR Default shell for new users (default /bin/sh)
--defaultgroup=STR Default group for new users (default ipausers). The
group must exist. Otherwise adding new users will fail.
--emaildomain=STR Default e-mail domain new users
Search tuning options. These impact how much data is searched through and
how many records may be returned on a given search.
--searchtimelimit=INT Max. amount of time (sec.) for a search (> 0, or -1 for
unlimited)
--searchrecordslimit=INT Max. number of records to search (-1 is unlimited)
Server Configuration.
--enable-migration=BOOL Enable migration mode
--pwdexpnotify=INT Password Expiration Notification (days)
The password notification value is stored here so it will be replicated.
It is not currently used to notify users in advance of an expiring
password.
Some attributes are read-only, provided for information purposes. These
include:
Certificate Subject base: the configured certificate subject base,
e.g. O=EXAMPLE.COM. This is configurable only at install time.
Password plugin features: currently defines additional hashes that the
password will generate (there may be other conditions).
