Make user home directory at gdm login

Question

I'm trying to make home directory at (RADIUS) user gdm login.

The auth is working right, but when I try gdm says that the user hasn't a home directory.

I tried to do that with pam_mkhomedir.so but is not working.

My /etc/pam.d/gdm file:

PAM-1.0
auth    sufficient  pam_radius_auth.so  
auth    sufficient       pam_nologin.so 
auth    sufficient        pam_env.so readenv=1 
auth    sufficient        pam_env.so readenv=1 envfile=/etc/default/locale
auth    sufficient  pam_succeed_if.so 
@include common-auth 
auth    optional        pam_gnome_keyring.so 
account sufficient  pam_radius_auth.so
@include common-account
session [success=ok ignore=ignore module_unknown=ignore default=bad] pam_selinux.so close
session optional        pam_limits.so 
@include common-session 
session [success=ok ignore=ignore module_unknown=ignore default=bad] pam_selinux.so open 
session optional        pam_gnome_keyring.so auto_start 
session required    pam_mkhomedir.so skel=/etc/skel umask=0022
@include common-password

I'm posting the configuration files:

Answer 1

Forgive me the dumb question, but have you installed the libpam-modules package which contains pam_mkhomedir.so? It's not installed by default on my copy of Ubuntu.

Failing that, you might want to try moving the line to /etc/pam.d/common-session, just in case the config files aren't being called in the order you expect. Your syntax looks correct, so it ought to work once you've got all the pieces in place.

You might also find the pam_debug module useful; it can let you shape exactly what path you want authentication to take.

Answer 2

I already notice that the real problem is that accounting/session is failing because the radius user has not an entry at /etc/passwd

I'm currently trying to do adduser by libpam_script.so plugin. Maybe it's the solution ;)
