Hi,
which AD (exact version) are you using 2003 (without R2?) Did you try different AD versions?
Did you install SFU3.5?

there are a couple of differences in the schema and I don't know how to configure winbind in regards to the mapping of attributes (like in nss_ldap or ldapux)

The UidNumber for my account in AD is 20045, but I keep getting 1000195.  I'm not so worried about the unixHomeDirectory or loginShell, it would be nice to get them, but the UID is a must.

Actually, the schema I am working with has been extended for both
methods! (Before I arrived).  The plan is to use rfc2307 - win2k3r2. 
Regarding where I got those settings, I have read countless man pages, howto's,
wiki's and forum threads to put it all together.  The main issue is the fact that I am using
an oldish version of samba, and since the release of 3.3.x I believe
things have gotten much easier, have you tried adex?.  Check out:
http://samba.org/samba/docs/man/manpages-3/idmap_adex.8.html

Other points of reference:
http://samba.org/samba/docs/man/manpages-3/idmap_ad.8.html

The only issue I have with having to use the ldap backend is the fact that I would need to hardcode the ldap server.  With winbind, all you need to supply is the realm & domain, then winbind takes care of which server to connect to, so it wont be limited to 1 server.

Let me know if you make any progress.

Thanks
