samba - Mar 2003 - Authentication error on weekends

Hi

	I have a Linux (RH 7.0), and I'he configured on smb server one share to
only one NT user. This user is a tool used for  file-transfer from MVS to
Windows using UNC file name convention. How I don't know the user's
password, I using SERVER security on smb.conf to validate the user. The
server that validate the user is the same where file-transfer tool runs.
During the workdays, it works fine, validating the user and tranfering the
files correctly, but on saturday, after 1:00PM, the server try to connect to
Linux, but the user is not validated, aborting the process.
	On SAMBA log, I found these lines every weekend:

2003/03/01 13:14:02, 0] passdb/pdb_smbpasswd.c:pdb_getsampwnam(1367)
 uname to open passdb database.

	It's the first message after 01:00PM, and persists until the STOP/START of
smb services.
	Any ideia about is happening??

Thanks

What are the security settings on this users' account on the daomain
controller? Are login restrictions enabled in any way? Does this user have
day and time based lock-out settings undet NT/2K?
