Hi Joe,

I believe that RH 7.1 uses the centralized /etc/pam.d/system-auth
file. You can set you /etc/pam.d/samba file to mimic /etc/pam.d/login
or the like.

Here's my /etc/pam.d/samba
auth       required	/lib/security/pam_nologin.so
auth       required	/lib/security/pam_stack.so service=system-auth
account    required	/lib/security/pam_stack.so service=system-auth
session    required	/lib/security/pam_stack.so service=system-auth

The pam_stack.so module invokes the specified service (system-auth in
this case which means that you must have a /etc/pam.d/system-auth file).

Here's my /etc/pam.d/system-auth:
#%PAM-1.0
# This file is auto-generated.
# User changes will be destroyed the next time authconfig is run.
auth        required      /lib/security/pam_env.so
auth	    sufficient	  /lib/security/pam_winbind.so debug
auth        sufficient    /lib/security/pam_unix.so use_first_pass
likeauth nullok
auth        required      /lib/security/pam_deny.so

account	    required	  /lib/security/pam_winbind.so
#account     required      /lib/security/pam_unix.so

password    required      /lib/security/pam_cracklib.so retry=3
password    sufficient    /lib/security/pam_unix.so nullok use_authtok
md5 shadow nis
password    required      /lib/security/pam_deny.so

session     required      /lib/security/pam_limits.so
session     required      /lib/security/pam_unix.so

Note the pam_windbind entries and the auth pam_unix entry with the
"use_first_pass"
argument. You could probably replace the pam_unix stuff with pam_pwdb
if you prefer that. Anyway, this configuration works for me using
swat and, in particular, correctly authenticates local/nis users vs.
domain
users.

Hope this helps.
