Greeting Monks,

I'm writing account synchronization scripts, and I'm not sure how to allow plugins.

Each account has flags stating which queries it was a part of, so someone might be part of a staff_ft query and a student query or whatever. I have a file that lists the queries and then lists the permissions granted by the queries (i.e, login, email, wireless access). I now need to write the logic to set and unset the actual LDAP permissions.

I have an idea, but it seems horribly ugly and wrong, so I'd really like a better one.

Create a package, AccountPermission with something like:
sub new {
my $class = shift();
my $self = bless( { }, $class );
return( $self );
}

To add a permission type, such as login, one would create a login.pm file that would inherit AccountPermission. One would then create two subs, run_if_permission_present and run_if_permission_absent.

All of these would be a in a local lib directory. From the main program, I'd get the directory contents to get the list of all permission plugins and put it into a Set::Scalar.

For each of them, I'd load them in an exec to catch any dies and then create a new of each and then can both function names. I _think_ that this would make sure that the files were reasonably well behaved.

And then do a:
$permissions_to_be_set = $set_of_known_permissions->intersection($permissions);
$permissions_to_be_unset = $set_of_known_permissions->difference($permissions);

Then then run the applicable methods.

I don't see any reason for it not to work. The main part that makes most of my ideas fail is that I need a complete list of plugins, as I need to be able to make sure that if login permissions are removed, the login plugin gets to know that and removes the applicable ldap flags.
