Greetings,

I have a fresh install of 2004.2 i686 with samba and winbind connected to a 2000 AD network. I have joined the domain and am getting back users and groups from it. Now, I would like all pam services to use winbind (login, ssh, etc).

My understanding is that the easy way out is to cp system-auth-winbind to system-auth and away you go.

When logging in tty, I am accepted and then immediately logged out. Logging as follow:

Code:
Sep 16 09:17:53 [pam_winbind] user 'trichar' granted acces
                - Last output repeated twice -
Sep 16 09:17:53 [login(pam_unix)] session opened for user trichar by (uid=0)
Sep 16 09:17:53 [login(pam_unix)] session closed for user trichar
S


When logging into ssh, I get:
Code:
Sep 16 09:54:04 [sshd] error: Could not get shadow information for trichards
Sep 16 09:54:04 [sshd] Failed password for trichards from 200.122.192.83 port 4544 ssh2
Sep 16 09:54:07 [sshd] error: PAM: Authentication failure for trichar from mis010.yada.yada.com
Sep 16 09:54:07 [sshd] Failed keyboard-interactive/pam for trichar from 200.122.192.83  port 4544 ssh2


Also, I tried manually changing /etc/pam.d/login to the way suggested in the samba docs. This gives the same result for tty login as above.

Am I correct in assuming this is the way intended to change all pam auths?

Any help greatly appreciated.

Thx,

_Terry

The problem here was that I did not uncomment this line in smb.conf:
Code:
template shell = /bin/bash

Consequently, /bin/nologin was run.

To summarize: once uncommented, you need only to replace system-auth with system-auth-winbind, and away you go.

For your next question of how to restrict access, well go here:
