Current approach does import users and groups; it only fails to assign 
users to groups properly. It can do already, but I would prefer less 
manual interaction.

I am not sure what I am "bending".

The classic upgrade did fail in exactly the same way even when I tried 
to do it literally as the corresponding guide tells:


(i.e. while keeping same workgroup name)

All I did was to ensure the new domain with unique SID is generated. 
 From the viewpoint of LDAP database, domain SID matches groups/users 
SID, so a) why the above problem b) why classic upgrade *does* copy 
users/groups anyway?
