I don't see that as an option in authconfig (or smb either now).  Are
there examples of how to set that up?  And does apache have to be
configured separately?

I thought 'sufficient privs' was an admin account in AD.  I don't
have/want that, and I'd prefer for the people running the AD servers
to continue to not know which linux servers are bouncing password
checks their way.

Maybe, if you have krb stuff passed through to a joined AD.  I was
hoping NTLM would still work.  And I want it to also work
transparently with local linux accounts that don't exist in AD.
