samba - Nov 2003 - unable to open passdb database

Hi all!
I'm having some wierd problems with my Samba v2.2.3a install on a 
Slackware 7 box. The Samba server is a member of an NT 4 Domain and I am 
having intermittent drive mapping problems. We have a logon script that 
maps several drives for users on our NT 4 box. Those drives are on our 
Samba server.

Sometimes when the script runs I get 1326 errors on my workstations 
(Win2k SP2), and am prompted to enter my password for the share. When I 
enter my password it still fails. Its almost as though the Samba box 
can't find the NT4 PDC, but there isn't a loss of connectivity between 
the linux server and the NT4 PDC.

This is what I get in the samba log:

[2002/06/03 16:03:46, 0] passdb/pdb_smbpasswd.c:pdb_getsampwnam(1367)
   unable to open passdb database.
[2002/06/03 16:03:46, 1] smbd/password.c:pass_check_smb(555)
   Couldn't find user 'caseyl' in passdb.

Here's an excerpt from my smb.conf:

[global]
         wins server = 192.168.100.5
         domain master = no
         dns proxy = no
         encrypt passwords = yes
         socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
         max log size = 50
         preferred master = no
         security = server
         password server = rrpdc1
         veto files = /.*/ /.Apple*/ /.bin/ /Network Trash Folder/ 
/TheVolumeSettingsFolder/ /TheFi
ndByContentFolder/Icon?/Desktop/DesktopFolderDB/
         delete veto files = Yes
         local master = no
         workgroup = RR
         server string = LVFS Samba [%v, %h]
         log level = 1
         log file = /usr/local/samba/var/log.%m
         netbios name = LVFS
         os level = 0

[homes]
    comment = Home Directories
    browseable = no
    writable = yes

[public]
         path = /export/fs/PUBLIC
         writable = yes
         only guest = yes
         create mode = 0666
         directory mode = 2777
         comment = Public Folder (world writable)
         printable = no
         public = yes

[depts]
         comment = Department Folders
         path = /export/fs/depts
         writable = yes
         valid users = @users
         write list = @users
         create mode = 0660
         directory mode = 2770
         admin users = caseyl

Any help would be greatly appreciated.

Hi
I recently setup samba 2.2.5-1 on a Redhat7.2 box. I
added a user same as on my w2k machine. everything
seems ok but when i try to login to linux box via
neighboorhood it keeps asking password and i can not
login anyway.

When i alanyzed the log file the error is as below:

[2002/07/30 11:59:39, 0]
passdb/pdb_smbpasswd.c:pdb_getsampwnam(1367)
  unable to open passdb database.
[2002/07/30 11:59:39, 0]
passdb/pdb_smbpasswd.c:pdb_getsampwnam(1367)
  unable to open passdb database.

my conf file is as simlple as possible and like below:
-----------------------------------------------------
# Global parameters
        workgroup = WORKGROUP
        encrypt passwords=yes
[test]
        comment = For testing only, please
        path = /export/samba/test
        read only = no
        guest ok = yes
-----------------------------------------------------

I ve added the user with 
smbpasswd -a username
command as same user and pass on my w2k machine.

Can anybody help me figure out this problem please?
Thanks
Deniz

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
[2003/11/05 16:29:58, 10] passdb/pdb_smbpasswd.c:pdb_getsampwnam(1346)
  pdb_getsampwnam: search by name: testuser
[2003/11/05 16:29:58, 10] passdb/pdb_smbpasswd.c:startsmbfilepwent(167)
  startsmbfilepwent_internal: opening file /etc/samba/smbpasswd
[2003/11/05 16:29:58, 2] passdb/pdb_smbpasswd.c:startsmbfilepwent(170)
  startsmbfilepwent_internal: unable to open file /etc/samba/smbpasswd.
Error was No such file or directory
[2003/11/05 16:29:58, 0] passdb/pdb_smbpasswd.c:pdb_getsampwnam(1369)
  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.
