Re: samba / UNIX password sync

you might want to consider a slightly different approach to your setup,

-use pam_smb to authenticate users on your linux system using the windows
user database
-use nss  (/etc/nsswitch.conf)  to get userinformation from files/nis) You
still need the windows usernames available in passwd/nis
      for information like homefolder/shell/uid/gid

in smb.conf use server or domain security.  (domain is better but samba
must join the domain first)
this enables samba to authenticate incoming connections using the windows
user database

This way, all authentication is done using windows accounts,  no password
sync is needed anymore!

Hi all.

I am running very old version of samba (2.2.7) and cannot upgrade just yet,
must make this work as it is (if possible).

After playing a bit with pam modules, I got first part of what I want to do
going - windows user is able to change domain password from windows.
However, this change never gets synced to Linux password, although (I
configuration is OK. Can someone give me some pointers to what else I need
to look at? Current relevant config is:

Server: Red Hat 7.1 / samba-2.2.7-2.7.2 (compiled from RH source with some
extra options, --with pam-smb_passwd included)
Client: Windows 2000 / some XP

# The PAM configuration file for the `samba' service
auth       required     /lib/security/pam_smbpass.so nodelay
account    required     /lib/security/pam_pwdb.so audit nodelay
session    required     /lib/security/pam_pwdb.so nodelay
password   required     /lib/security/pam_smbpass.so nodelay

security = user
encrypt passwords = yes
smb passwd file = /etc/samba/smbpasswd
unix password sync = Yes
passwd program = /usr/bin/passwd %u
passwd chat = *New*password* %n\n *Retype*new*password* %n\n
pam password change = yes
obey pam restrictions = yes

What am I missing? Help appreciated,
