Installed a fresh 14.04 deskop, and joined to a Samba domain (server running 12.04 samba). Having setup samba as a member server with winbind, I can now enumerate Domain users and login via SSH. When logging in via the GUI desktop, the above happens:
- authentication success, the desktop starts coming up
- but them bombs out and comes back to the GUI login.

I commented out the wallet lines in /etc/pam.d/lightdm /etc/pam.d/lightdm-greeter, rebooted, but that didn't help.

/var/log/auth.log doesn't help much
