InformationDefines the minimum number of weeks before a password can be changed.
The minage attribute prohibits users changing their password until a set number of weeks have passed.
The AIX community prefers to rely on the AIX attribute histexpire rather than a historical minage value.
Historically, the minage attribute has been used to prevent a user from write a script to spool through histsize passwords, and then return to the same password as before. The attribute histexpire overrides histsize. Therefore, there is no need to force a user to request assistance from system administrators in order to reset a poorly chosen password, or in the case of special accounts that policy states passwords are meant for 'one time use'.
Again, since AIX has a different way to prevent scripted password re-cycling, the need for minage is not longer warranted.
SolutionIn/etc/security/user, set the default user stanza minage attribute to 1:
chsec -f /etc/security/user -s default -a minage=0
This means that a user can change their password at any time.
