Hi, thanks for your reply.

I read your conversation with Michael Adams a few days ago. The fact
that winbindd does not pull unixHomeDirectory and other attributes is
of course a bug. But I don't manage to get it to pull uid- and
gidNumber at all from AD. :)

I also noticed that the extra idmap info in smb.conf doesn't matter.

Is your ADs NetBIOS-name the left-most part of the name of your dns
domain (EXAMPLE, example.org or SAMDOM, samdom.example.org)? If so,
that might be the reason I can't get it to work. My dns domain is
samdom.example.org and NetBIOS-name is EXAMPLE. Or is it a more
obvious error which I don't see?

For the moment I've got no reason to revert to version 4.1.3 though.
