Hi List,

I'm installing a Samba server with the intended purpose of serving files to
Windows users with seamless authentication on the smb server.
For that, I've been reading and following every single google search result
regarding the subject, but it seems I'm stuck at some point where other
people are not blocked ...

To summarize, I have these commands OK:
# kinit admin_user(a)DOMAIN.EXAMPLE.COM
# klist (ticket ok)
# net join ads -S server -U admin_user
# wbinfo -u and -g (both showing "DOMAIN\...")
# wbinfo -t (succeeded)

I configured PAM to use winbind, and to test it I'm using ssh with the same
config as I will for samba

Here's what I get when I try to ssh into my smb server using my AD
Jan 18 15:34:18 smb sshd[9157]: pam_winbind(sshd:auth): getting password
Jan 18 15:34:18 smb sshd[9157]: pam_winbind(sshd:auth): request failed:
Named pipe dicconnected, PAM error was System error (4), NT error was
Jan 18 15:34:18 smb sshd[9157]: pam_winbind(sshd:auth): internal module
error (retval = 4, user = 'DOMAIN\myusername')
Jan 18 15:34:18 smb sshd[9157]: pam_unix(sshd:auth): authentication failure;
logname= uid=0 euid=0 tty=ssh ruser= rhost=
user= DOMAIN\myusername
Jan 18 15:34:20 smb sshd[9157]: Failed password for DOMAIN\myusername from port 50872 ssh2

Any idea on what this error (NT_STATUS...) means ?

Also when trying this I get an error:
smb:~# wbinfo -a admin_user%admin_pwd
plaintext password authentication failed
Could not authenticate user henry_admin with plaintext password
challenge/response password authentication failed
error code was NT_STATUS_PIPE_DISCONNECTED (0xc00000b0)
error messsage was: Named pipe dicconnected
Could not authenticate user admin_user with challenge/response

Here's my PAM config:
auth sufficient
auth required use_first_pass
account sufficient
account required
session required skel=/etc/skel/ umask=0022
session sufficient
session required
password requisite retry=3 type=
password sufficient nullok use_authtok md5 shadow
password sufficient use_first_pass
password required

Any help would be greatly appreciated.
