Description Daniel Walsh 2011-08-09 12:52:16 UTC
This is causing the welcome program to run as unconfined_t and prevents confined users from logging in.

Removing pam_selinux from the stack (as well as pam_namespace) changes the entire xdm suite to run as xdm_t as it should and allows me to login as staff_t not, unconfined_t.

If you want to use pam at all, you probably want a very limited stack.

Comment 1 Ray Strode [halfline] 2011-08-09 18:40:31 UTC
i'll push a fix now that culls the pam list a bit in the service file, to prevent the greeter from running unconfined.

There's another problem where the pam conversation is run in the main slave process instead of a welcome specific subprocess, so the subsequent worker processes are run as if they're part of the welcome session.  I'll address that when I get time to work on this upstream.
