[Samba] PAM Error 9

Hi all
I have set my Samba server up to join an AD realm. Winbind is working 
fine and I am able to use it for authentication as needed. When I try to 
connect to one of my shares via a Windows client, I get the following error:

[2004/11/04 11:57:54, 0] auth/pampass.c:smb_pam_account(573)
   smb_pam_account: PAM: UNKNOWN PAM ERROR (9) during Account Management for
User: MYDOMAIN+room1

   smb_pam_error_handler: PAM: Account Check Failed : Authentication service
cannot retrieve authentication info.

   check_ntlm_password:  Authentication for user [room1] -> [room1] FAILED
with error NT_STATUS_LOGON_FAILURE


My smb.conf file looks something like this:

[global]

winbind separator = +
winbind uid = 10000-20000
winbind gid = 10000-20000
winbind cache time = 15
winbind enum users = yes
winbind enum groups = yes
template homedir = /home/%U
template shell = /bin/false
winbind use default domain = yes

    panic action = /usr/share/samba/panic-action %d
#       passwd program = /usr/bin/passwd %u
         printing = bsd
         netbios name = proxy
         dns proxy = no
         syslog only = no
         name resolve order = lmhosts host wins bcast
         encrypt passwords = true
#   passdb backend = smbpasswd guest
  socket options = IPTOS_LOWDELAY TCP_NODELAY SO_SNDBUF=4096 SO_RCVBUF=4096
         short preserve case = yes
         printcap name = /etc/printcap
         invalid users = root
         max log size = 1000
         obey pam restrictions = yes
#       passwd chat = *Enter\snew\sUNIX\spassword:* %n\n
Retype\snew\sUNIX\spassword:* %n\n .
         security = ads
         password server = DC1
         realm = MYDOMAIN.BLAH
         preserve case = yes
         unix password sync = false
         workgroup = MYDOMAIN
         server string = %h server (Samba %v)
         syslog = 0;
         guest account = nobody
         load printers = yes


For what it's worth, my /etc/pam.d/samba file is as follows:
auth        required      /lib/security/pam_env.so
auth        sufficient    /lib/security/pam_unix.so likeauth nullok
auth        sufficient    /lib/security/pam_winbind.so use_first_pass
auth        required      /lib/security/pam_deny.so

account     required      /lib/security/pam_unix.so
account     sufficient    /lib/security/pam_winbind.so use_first_pass

password    required      /lib/security/pam_cracklib.so retry=3 type# Note: The
above line is complete. There is nothing following the '='
password    sufficient    /lib/security/pam_unix.so \
                                              nullok use_authtok md5 shadow
password    sufficient    /lib/security/pam_winbind.so use_first_pass
password    required      /lib/security/pam_deny.so

session     required      /lib/security/pam_limits.so
session     sufficient    /lib/security/pam_unix.so
session     sufficient    /lib/security/pam_winbind.so use_first_pass`


Interestingly enough, if I connect using smbclient and force it to use
kerberos with the -k option, I am able to connect. It's not until I try 
to use NTLM that I receive the error.

Any suggestions?
Cheers
Richard

[Samba] PAM Error 9

Richard,

What entries did you put in /etc/nsswitch.conf?
Does 'getent passwd' return the ADS user info?

[Samba] PAM Error 9

John
Thanks for your reply.  winbind authentication is working fine. I am using 
pam_winbind.so for POP3 authentication. getent passwd also returns all the 
users with no problems. If I run 'wbinfo -a username%password for a user 
on the Windows DC, all works fine.
