samba - Aug 1999 - Couldn't set effective gid to 65534 currently set to (real=0,eff=0)

Here is a snippet from my /var/log/smb:

  smbd version 2.0.5a started.

  Looks like your OS doesn't like high gid values - try using a different
account

  Can't become connected user!

I can not connect to my samba box. Every time I try to connect, the smbd tries
to change its uid to that of the connecting user, in this case it a guest
connection, so is changing to nobody, with a uid of 65534.

This is a Debian box, running the debian package of samba 2.0.5 with it running
from inetd, I get the same if I try and run it as a daemon.

Can anybody help? Can you CC me with replies (I am not on the list). Is this a
known bug? I have experienced this on two machines, a 2.0.36 and 2.2.10 box.

What can I do, how do I get it working?
