samba - Oct 2004 - samba 3 with ads not authenticating against ADS trusts

I've got a samba 3 ads domain member server that is not able to
authenticate users in trusted domains of the ADS domain of which it is
a member.

Windows 2000 ADS PDC A trusts a Windows NT-4 domain B and a Windows
2000 ADS domain C
Solaris 9 Samba 3.0.6 member server of ADS domain A

If I use getent passwd on the Solaris 9 server, I get all the users in
Domain A and B , but no in Domain C, same thing with getent group,
wbinfo -u and wbinfo -g.

So winbindd is not "seeing" the users and groups on one of the trusted
domains... and if I try to map a share from a Windows XP client, using
one of the users in the domain winbindd CAN "see", I'm getting
errors
in log.smbd.

domBuser is a member of the NT4 domain, domain B, which winbind lists
in getent and wbinfo, but I can't map using those users.

Any ideas?
