Has anyone else gotten samba functioning with idmap_ad and multiple domains?
In our environment we have a domain with two child domains. There is one child
domain for students, and another for faculty staff. Our servers are joined to
the student domain, but need to be able to enumerate users in the staff domain.
When attempting to lookup a user (wbinfo -i 'NAU\car3') that only exists in
the staff domain, I see this in the log.winbindd-idmap:

Both the student and faculty domains have the rfc2307 attributes set, so I am
unsure as to why I am only able to lookup users in the NAU-STUDENTS domain and
not the NAU domain.
Any thoughts?
Thanks,
Christian
