Comment 1 Jason Vas Dias 2006-04-26 10:04:54 EDT
Yes, I can confirm this problem with pam- .

After upgrading to rawhide-20060425 and pam-, pam_console no longer
sets the ownership of /dev/console and /dev/dsp to the console login session
user .  As a result, audio is disabled, and 'xterm -C' fails.

/etc/pam.d/{gdm,kdm} contains 'session optional pam_console.so' which used to
set the ownership of /dev/dsp to the login user OK, when I started a X (KDE)
session as a NIS user.

Now, I get these messages in /var/log/secure when logging into X as a NIS user
with kdm, and the ownership of /dev/dsp is not set correctly (it remains root):

pam_console_apply[xxxx]: unknown class "ircomm" at line 58 in

kdm: :0[xxxx]: pam_console(kdm:session): handler '/sbin/pam_console_apply'
returned 1 on exit

Commenting out line 58 in /etc/security/console.perms.d/50-default-perms
fixes the problem, and /dev/dsp and /dev/console then have correct ownership
after login with kdm/gdm .

Comment 3 Jon Masters 2006-04-26 13:41:40 EDT
Yup, commenting out that permission fixed the problem I described in BZ 189994
where /dev/pmu had the wrong ownership also.
Comment 4 Tomas Mraz 2006-04-27 03:19:54 EDT
Should be now fixed, also the pam_console_apply should now handle such lines
gracefully, skipping them and not exiting.
