Technically 3.0.23b since there was still some
ambiguity in the previous 3.0.23 releases.

- -> seems for me from "b" on, right?

3920 is fixed. But understand 'winbind use default
domains' was never intended for anything except PAM &
NSS. Internally Samba must deal with qualified names
in order to correctly resolve them to SIDs. So even an
assumed domain name gets qualified. However, in smb.conf
the responsibility is on the admin to remove ambiguity
by fully qualifying the name. This has nothing to do
with BUG 3920 really.

No. 'winbind use default domain' is a convenience parameter
for PAM and NSS applications. The domain user still exists
and getpwnam("DOMAIN\user") still succeeds. We always
try to look up the qualified version first.
