Testing this will be hard, but it should be tested that:

1. expiration by ppolicy is still working
2. expiration at posix expiration date is working
3. warning of expiration by ppolicy is working
4. warning of expiration by posix is working
5. expiration also locks out of the webservice

@jswaelens From what I understand from fd-plugins#3397 (closed) , it is expected that ppolicy expiration behave the same as bad password. To avoid this we’d need to use LDAP controls, which are only available in PHP>=7.3 : https://www.php.net/manual/en/function.ldap-bind-ext.php

The case where the message is supposed to be different is when a password change is forced on the user using the option in ppolicy user tab. The code for this seems wrong so I will push a fix.
