[Samba] Trouble login into a Samba 3.0.21c from Windows XP Professional SP2

[Andres Tarallo]

Hi !!!  

I've had configured a samba 3.0.21c PDC on a SuSE 9.3 with the RPM I've
downloaded from http://www.samba.org.  My PDC uses LDAP as backend.  I
have a Windows 98 client and a Windows XP Professional SP2 client. The
windows 98 client lets all the users log in happily and everything works
as expected, the Windows XP has a very weird an annoyuing behaviour.

After booting both the server and the XP Professional I can log into the
the PDC, as desidered. Once I chose to finish the session and log as a
new user the I get a Message that says something that the server
prevents from logging (I use the spanish edition of Windows XP, I can
provide the exact message).  On the server side IMHO the relevant
message is this:  _nets_auth2: creds_server_check failed:  Rejecting
auth request from client MACHINE machine account MACHINE$

Any help or ideas will be very welcome.
