fix to regard the password-last-changed information from the auth system - if provided, and thus be able to react on forced password changes triggered from auth system. set password-last-changed info in authsystem on password change. when trying to force the user to change his password upon next login as admin from within egrouware, try to set the 0 value within the authsystem as well (in ldap rights are required for admin (or user) to set/alter the shadowlastchange attribute)
