[Samba] NetBIOS name of 15-characters still doesn't work

[Ken Cross]

Sambaens:

We have confirmed that 15-character NetBIOS names cannot join a domain
in any of the following platforms:

  Samba 2.2.3a on Solaris
  Samba 2.2.2  on NetBSD
  Samba 2.2.3a on NetBSD
  Samba 2.2.4-pre on NetBSD (May 1 version)
  Samba 3.0    on NetBSD (May 1 version)
  Samba 2.2.3a on Linux 7.2

We've tried with multiple PDCs (NT4 and Win2K).  Windows clients can
join just fine.  14-character names work OK.  I've traced the packets
and they're identical, except that the PDC returns "ACCESS_DENIED" with
the 15-character names.  We've done it with a minimal smb.conf:

 [global]
 netbios name = A23456789012345
 workgroup = NT4DOMAIN
 security = domain

Has anyone seen anything similar?  Any ideas?
