samba - Nov 2010 - workgroup name length limitation in samba 3.5.6...

Hi,
      I face problems trying to input workgroup name lengths more than 15
characters in smb.conf and run nmbd. I am using samba 3.5.6 (source3 version of
nmbd in 3.5.6 package).

      This was faced by a user earlier as per link
http://www.mail-archive.com/samba at lists.samba.org/msg22773.html  and solution
provided by Jeremy Allision as per link http://www.mail-archive.com/samba at
lists.samba.org/msg22776.html  dated 2003.

     Yet in 3.5.6 version still the namelength restriction for workgroups seems
to be there and nmbd can take only workgroups with name length upto 15
characters.  Could somebody point out where I may be erring?


Thanking You and Regards,
Vijay

See some Microsoft documentation. NetBIOS names are 16 characters in
length, up to 15 (space padded) defined by the user, the 16th defines
the service.

This is not a Samba limitation, this is by NetBIOS design, which Samba  
of course respects:

Look at this page:
http://en.wikipedia.org/wiki/NetBIOS

"NetBIOS names are 16 octets in length and vary based on the  
particular implementation. Frequently, the 16th octet is used to  
designate a "type" similar to the use of ports in TCP/IP. It is called
the NetBIOS Suffix (read below) or "resource type", and is used to  
tell other applications what type of services the system offers."


Looking at your smb.conf, it seems to me that you are mixing up  
NetBIOS domain names and FQDNs (Fully Qualified Domain Names). They  
are not the same thing and should be used in their proper place.
