[Samba] pam_winbind problems

[Shane Drinkwater]

Hello,
I am have some interesting problems with the pam_winbind portion of samba
3.1. wbinfo -u and getent passwd
works but when I login I get the following messages in /var/log/messages.
Jan  5 11:09:36 hermes pam_winbind[9014]: write to socket failed!
Jan  5 11:09:36 hermes pam_winbind[9014]: internal module error (retval = 3,
user = `CSQ+shane'
Jan  5 11:09:36 hermes PAM_pwdb[9014]: check pass; user unknown
Jan  5 11:09:37 hermes login[9014]: FAILED LOGIN 1 FROM 172.27.1.223 FOR
CSQ+shane, User not known to the underlying authentication
module.
my login in /etc/pam.d is
auth       required     pam_securetty.so
#auth       required    pam_stack.so service=system-auth
auth       required     pam_nologin.so
auth       sufficient   pam_winbind.so
auth       required     pam_pwdb.so use_first_pass shadow nullok
#account    required    pam_stack.so service=system-auth
account   sufficient    pam_winbind.so
#password   required    pam_stack.so service=system-auth
password   required     pam_pwdb.so use_first_pass shadow nullok
#password   required     pam_winbind.so
session    required     pam_stack.so service=system-auth
session    optional     pam_console.so
 
I have also installed samba on two other LINUX boxes with the same error. Is
this a bug or am I doing something wrong??
                        Thank You for your Time!
