Server configuration

Manage the default values that IPA uses and some of its tuning parameters.

NOTES:

The password notification value (--pwdexpnotify) 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 only 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 plug-in features: currently defines additional hashes that the

password will generate (there may be other conditions).

When setting the order list for mapping SELinux users you may need to

quote the value so it isn't interpreted by the shell.

EXAMPLES:

Show basic server configuration:

ipa config-show

Show all configuration options:

ipa config-show --all

Change maximum username length to 99 characters:

ipa config-mod --maxusername=99

Increase default time and size limits for maximum IPA server search:

ipa config-mod --searchtimelimit=10 --searchrecordslimit=2000

Set default user e-mail domain:

ipa config-mod --emaildomain=example.com

Enable migration mode to make "ipa migrate-ds" command operational:

ipa config-mod --enable-migration=TRUE

Define SELinux user map order:

ipa config-mod --ipaselinuxusermaporder='guest_u:s0$xguest_u:s0$user_u:s0-s0:c0.c1023$staff_u:s0-s0:c0.c1023$unconfined_u:s0-s0:c0.c1023'
