Schema-API

[Michael Ströder]

Dear list members,

please review the schema API in Lib/ldap/schema.py. There's also a 
demo script Demo/schema.py.

I've tested it with OpenLDAP 2.0.x and 2.1.x, an Innosoft server 
and some Siemens Dir/X servers I found. It still chokes on 
Netscape/iPlanet/Sun Directory Servers etc. with non-numeric "OID" 
but now with a nice exception.

Up to now I only addressed the issues with finding the mandantory 
and optional attribute types to a given list of object classes. 
It's still far away from being a complete schema support.

Please comment!

Ciao, Michael.
