[Samba] Samba 3 and Windows 200 Server

[tbey at tbey.com]

I am trying to get the MS SQL Serves Login to authenticate users.  I ger
the following error on the Windows client:
Connection failed:
SQLState: 28000
SQL Sever Error: 18456
Login failed for user XXXXXXX\XXX

When I look at the samba logs I ger the following information:

rpc_server/srv_pipe_hnd.c: process_request_pdu
procs_request_pdu: failed to do schannel process

rpc_server/srv_pipe.c: api_pipe_ntsec_process
failed to decode PDU

Is there any one who can point me in the right direction.

Thanks
