The NT entity relationship model is actually based on the one in OS/2.  
Modern editions of both have their common ancestry in old OS/2 LAN Manager.
Until Novell releases NDS for NT, there really is no directory service 
available for NT.  The entity domain relationships are NOT a directory 
service.
IBM does offer industry standard X.400 directory services for OS/2.  However, 
this is an extra cost option.
