          Priority: medium
            Bug ID: 67837
          Assignee: wayland-bugs at lists.freedesktop.org
           Summary: [weston-launch] default pam configuration breaks on
                    fedora 19
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: joe.konno at linux.intel.com
          Hardware: All
            Status: NEW
           Version: unspecified
         Component: weston
           Product: Wayland

After building wayland and weston 1.2.0, weston-launch does not work "out of
the box" on a (fairly) pristine Fedora 19 installation. "Fairly" because I
disabled selinux shortly after installation.

The first error encountered (stdout/stderr weston-launch):

  failed to open pam session: 14: Cannot make/remove an entry for the specified
session

And /var/log/secure:

  Aug  6 10:18:30 $host weston-launch: pam_loginuid(login:session):
set_loginuid failed
  Aug  6 10:18:30 $host weston-launch: pam_unix(login:session): session opened
for user $user by (uid=1000)

I did a web search, found a cheap work-around for the pam issue here:
  https://ask.fedoraproject.org/question/25453/weston-launch-start-problem/

Which entails commenting out a line in the default pam configuration file:
  # #weston-launch# session    required     pam_loginuid.so

The expectation is that weston-launch "just works" with sufficient permissions
(all documented) are granted. However, that is not the case on Fedora 19.
