> Currently , it is possible to define a ACL (user and groups) for a service.
> To temporarily remove authorization for a set of users, administrator needs
> to remove the users from the specific group and this may be a lengthy process
> ( update ldap groups, flush caches on machines).
> If there is a facility to define a reverse ACL for services, then
> administrator can disable users by specifying the users in reverse ACL. In
> other words, one can specify a whitelist of users and groups as well as a
> blacklist of users and groups.
> One can also specify a default blacklist to disable the users from accessing
> any service.
