I know this is an old thread, but I just got a new idea.

What if I create a NT4 style domain on our SAMBA servers, So I have a Samba
NT4 style PDC. Then I create a NT4 style trust with the AD domain. This
way, I don't use kerberos nor DNS SRV records, both of which are needed if
I would go the AD route. But now, users from the AD domain can access Samba
