Sorry if this is a simple question but I have been struggling for many days
trying to samba-3.0.2rc2 working with a win2k AD

wbinfo -t works
wbinfo -u works
wbinfo -g works

getent passwd username works

sharing dirs works

in fact everything seems to work with the exception of a users directory being
created using pam_mkhomedir.so

I am running on Redhat 9   with Samba 3.0.2rc2

Samba was built using the following options   configure --with-quotas --with-pam

I presume it is something wrong with my pam config  which follows

#%PAM-1.0
auth       required     pam_securetty.so
#auth       required    pam_stack.so service=system-auth
auth       required     pam_nologin.so

session required pam_unix.so
session optional pam_lastlog.so
session optional pam_motd.so
session optional pam_mail.so standard noenv

I have tried many varations of this file from various postings but all to no
avail

the relevant part of smb.conf follow

        workgroup = LEARNINGDOMAIN
        realm = LEARNINGDOMAIN.ORG

        preferred master = No
        local master = No
        domain master = No
        dns proxy = No
        ldap ssl = no

if I try su - DOMAIN+Username from a shell prompt

I get the following reply

[root@store01 pam.d]# su - LEARNINGDOMAIN+Administrator
su: warning: cannot change directory to /home/LEARNINGDOMAIN/Administrator: No
such file or directory
-bash-2.05b$



So I get logged in but I remain in the current working directory

any advice gratefully received

[Samba] How do I get pam_mkhomedir to work

I'm using RedHat 9.0 and it works, here is what my files look like -

/etc/pam.d/login looks like this -   The authconfig tool in RedHat did
everything except the pam_mkhomedir.so bit.

#%PAM-1.0
auth       required     pam_securetty.so
auth       sufficient   pam_UNIX.so use_first_pass
auth       required     pam_stack.so service=system-auth
auth       required     pam_nologin.so
account    required     pam_stack.so service=system-auth
password   required     pam_stack.so service=system-auth
session    required     pam_stack.so service=system-auth
session    required     pam_mkhomedir.so umask=0022
session    optional     pam_console.so

My /etc/pam.d/gdm looks like this -

#%PAM-1.0
auth       required     pam_env.so
auth       required     pam_stack.so service=system-auth
auth       required     pam_nologin.so
account    required     pam_stack.so service=system-auth
password   required     pam_stack.so service=system-auth
session    required     pam_stack.so service=system-auth
session    optional     pam_console.so
session    required     pam_mkhomedir.so skel=/etc/skel umask=0022

/etc/pam.d/system-auth looks like this -

#%PAM-1.0
# This file is auto-generated.
# User changes will be destroyed the next time authconfig is run.
auth        required      /lib/security/$ISA/pam_env.so

account     required      /lib/security/$ISA/pam_unix.so

password    required      /lib/security/$ISA/pam_cracklib.so retry=3

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


I also use 'winbind use default domain = yes' in smb.conf.

pam_mkhomedir doesn't make deep directories ... does /home/LEARNINGDOMAIN 
exist?

And, you don't mention which pam config file you are editing, but it is 
most likely more useful to do this in system-auth, then if you set 'obey 
pam restrictions = yes' in smb.conf, samba will even make the home 
directories (or any app pam application with session support ...
