I think that my approach is a little bit different than others, I'm not trying 
to make a tool that will automatically map LDAP object with all its attributes 
to a python object, I'm aiming at solution where:

1. there is no magic, nothing happens without You knowing it, no auto mapping 
attributes from LDAP to python
2. we assume that user know what schema is defined on the server, it's not 
designed for cases where You first discover what is stored on server side and 
then adapt
3. server stores standardized data, this means that if You store user 300 
accounts, all of them are using the same set of object classes 
4. user to writes models and he describes what object classes and attributes 
he is going to use in those models
5. user models needs to follow server schema, if they don't he is going to get 
exception before anything happens

I don't need a solution for browsing LDAP data and dealing with every type of 
attribute that can be defined, I need a tool to easily work with large set of 
unified objects (like user accounts), creating user model with set of methods 
to deal with user accounts seems to me like a good way of doing this.
