In fact, this is the log at debug level 10 :
[2003/11/05 16:29:58, 1] smbd/password.c:server_validate(1101)
  password server  is not connected

  unable to open passdb database.

It seems that if the password server is not available, samba by design
falls back to smbpasswd... (I don't think I specified it so anywhere.)

And I can't understand why "server is not connected" after some time...

This is my smb.conf setting
      workgroup = MYDOM
      security = server
      password server = ADSERVER 
      encrypt passwords = yes

The following are commented out, should I explicitly do something? (more
than commenting out?)
#   smb passwd file = /etc/samba/smbpasswd 
#   unix password sync = Yes 
#   passwd program = /usr/bin/passwd %u 
#   passwd chat = ...... 
#   pam password change = yes
#   obey pam restrictions = yes

Initially users can use the share, change the password, then use the share
again without problem. But after some time, I get this error. (When I
click the samba machine, in the "Entire Network", a "Enter Network
Password" logon box pops up. It asks for "Connect As:" and "Password", but
no combinations work, and we see the above error in the log.

Strangely, if I restart smb server, users can connect to the share without
problem, without doing anything. 

We have some account lockout problem on the windows side, but it doesn't
seem to be the problem (especially because smb restart clears the problem 
temporarily), and I really wonder what's wrong.
