Description Nalin Dahyabhai 2007-06-25 14:50:06 UTC
Description of problem:
The third comment in bug #198623 points out that the keyring should be
initialized before the rest of the PAM session modules are called, but in
/etc/pam.d/remote, pam_keyinit.so called last.

Version-Release number of selected component (if applicable):

Comment 1 Nalin Dahyabhai 2007-06-25 15:34:11 UTC
Somehow I missed that the "login" configuration has the same problem, but
it appears to as well.

Comment 2 Karel Zak 2007-07-09 11:28:59 UTC
Well, there is also "pam_selinux close" that should be the first PAM session
module, I've moved the pam_keyinit behind the pam_selinux. Updated version:

auth [user_unknown=ignore success=ok ignore=ignore default=bad] pam_securetty.so
auth       include      system-auth
account    required     pam_nologin.so
account    include      system-auth
password   include      system-auth
# pam_selinux.so close should be the first session rule
session    required     pam_selinux.so close
session    optional     pam_keyinit.so force revoke
session    include      system-auth
session    required     pam_loginuid.so
session    optional     pam_console.so
# pam_selinux.so open should only be followed by sessions to be executed in the
user context
session    required     pam_selinux.so open
session    optional     pam_ck_connector.so


Comment 3 Karel Zak 2007-07-09 11:31:11 UTC
(Note, I'm changing this in devel & F7 now.)

Comment 4 Nalin Dahyabhai 2007-07-09 13:58:41 UTC
I think so -- the SELinux module doesn't interact with the keyring (to
double-check, running ldd on pam_selinux.so didn't list the keyutils library, so
I'm pretty sure), so that should be fine.

The important thing on my test box is that the keyring is set up before pam_krb5
is run, because it may put AFS session data in the keyring.
