Summary: LDAP auth and permissions

Initial Comment:
This is a continuation of my request about authorization...

I would like perm class to be compatible with permissions 
(or groups) stored in LDAP directories.

The current implementation needs a hardcoded list of 
permissions in local.inc. This is a huge problem when users 
are stored in LDAP and have their perms stored alongside all 
other userinfo in the directory. This means that you 
manually have to check the LDAP directory for new 
permission groups that have been created and add them to 
local.inc.

Making the perm class (and the auth class) more compatible 
with existing "corporate" user directories would be a great 
way to ensure a strong future for the library.

I have two suggestions for alternate implementations. I am 
not fully into the inner workings of the phpLib so I have to 
leave it up to you to figure out the best implementations to 
fit the library.

1. Have the perm class use LDAP and at initialisation 
retrieve a list of permission groups from the server and 
make the bitmap on the fly. (since the bitmap only used for 
comparison and not storage of perms.)

Something like this but probably connected to the LDAP 
class:

var $permissions;

	// connect...
	$ps=ldap_connect($this->ldap_host, $this->ldap_port);
	
	if ($ps) { 
		// admin bind...
		$r=ldap_bind($ps, $this->rootdn, $this->rootpw);
		// search for groups...
		$sr=ldap_search($ps,$this->basedn, $this-
>attrtype_perms."=".$this->attr_perms );
		// get matching entries
		$info = ldap_get_entries($ps, $sr);
		
		$bin=1;
		// test all results, and get uid and permissions...
		for ($i=0; $i<$info["count"]; $i++) {
			
			$permissions[$info[$i][$permid][0]] = $bin;
			$bin*=2;

		}
	}
	ldap_close($ps);


2. Replace the bit comparison in the perm class with a string 
comparison.
