We've got Winbind/Kerberos setup on RHEL for AD authentication. Working fine however I noticed that when a password has expired, we get a warning but shell access is still granted.
What's the proper way of handling this? Can we tell PAM to close the session once it sees the password has expired?
Example:
login as: ad-user
[email protected]'s password:
Warning: password has expired.
[ad-user@server ~]$
