11.3. Editing the Global Password Policy
A password policy can be selective; it may only define certain elements. A global password policy sets defaults that are used for every user entry, unless a group policy takes priority.
A global policy always exists, so there is no reason to add a global password policy.
11.3.2. With the Command Line
To edit the global password policy, use the pwpolicy-mod command with the attributes to change:
ipa pwpolicy-mod --attribute=value
For example:
ipa pwpolicy-mod --lockouttime=300 --history=5 --minlength=8
