[Samba] Sid S-0-0 is not in a valid format

[Adam Nielsen]

Hi all,

I'm trying to get winbind going on a different PC to the one I've
already got working, but I can't figure out why winbind won't work on
this other PC.  It mostly works (wbinfo works, net ads testjoin reports
OK) but "getent passwd" doesn't return anything.  The winbind log
reports this:

[2006/01/17 15:27:15, 1] nsswitch/winbindd.c:main(976)
  winbindd version 3.0.21rc2 started.

  request_len_recv: Invalid request size received: 1824

Does anyone have any idea what that means and how I can fix it?  I'm a
bit stuck - running winbind with -d9 doesn't help and it doesn't print
any debug messages when it receives a request so I can't see what's
happening.

Thanks,
Adam.
