[Samba] 15-character NetBIOS name won't join domain

[Ken Cross]

I just installed Samba 2.2.3a on Redhat Linux 7.2 with the same results
-- a 14-character NetBIOS name can join the domain, but a 15-character
name gets "ACCESS_DENIED".

Listed below are the trimmed-down output from log level 10.  The first
is the successful one, the second is the failure.
