Just a brief explaination, I need to know what fields are different and how to reproduce them if I choose to... let's SUPPOSE
Migrate data from /etc/passwd and /etc/group files
It would be nice knowing for ex if old sambaSID and new objectSID are the same thing, because I already know (from smbldap tools) how to calculate it

So I guess I can't use an ldif file made for NT4 for populating an AD, right?

How could I get an idea of what still needs to be done? AFAIK the project leader for this thing is in vacation

What I meant is would uid=myuser,ou=People,dc=mydomain still work?

Thank you, what I meant is pretty much what I asked in "Is ActiveDirectory fully retrocompatible with NT4?"
