When Active Directory was introduced (2K), it used a different DNS setup 
to what is used now, this changed when Windows 2003 was introduced, but 
they didn't enforce the dns upgrade. This meant that many people didn't 
upgrade the DNS when they upgraded the server. We are now seeing a few 
reports of problems like yours, normally when trying to join Samba as a 
DC to an existing Windows domain.

Samba initially used the 2K DNS, but quickly moved to the later DNS 
system, so, if mine is wrong, then everyone else's is wrong.

It seems to work correctly, until you try to join another DC.

If it is a bug and I do not accept it is, I doubt if it will be fixed, 
because if the DNS is correct, everything works correctly.

Will do, I will send it to you offlist.
