Ticket #39 - Account Policy Plugin does not work for simple binds when PAM Pass Through Auth plugin is enabled
    
    Bug Description:  The PAM plugin, if the bind was successful, aborts the pre and post op plugins.
                      This causes problems with post op plugins like Account Policy.
    
    Fix Description:  In do_bind(), still call the post op plugins even if the pre-op ones fail.
