[Samba] Problems using Samba 3.0.0 as ADS member server

[Eli Klein]

I have a linux box configured with samba 3.0.0 joined to my Win2k ADS 
domain.  I can succesfully use kinit and smbclient -k without entering a 
user/pass to connect to things on my network.

 From ANY client host (WinXP, Win2k, etc), I can't connect to my linux 
box.  The error I get is ALWAYS (this is after the client i'm on asks 
for a username/password and i enter it):

[2003/09/29 11:09:57, 1] smbd/sesssetup.c:reply_spnego_kerberos(218)
   Username <host.im.connecting.from>$ is invalid on this system

no other errors.  I've tried setting client use spnego = no with no luck.

Any suggestions?

TIA for any help.
