Description of problem: in booting message unkonwn class "ircomm" at line 58 in /etc/security/console.perms.d/50-default.perms $ cat /etc/security/console.perms.d/50-default.perms | grep ircomm <irda>=/dev/ircomm* <console> 0600 <ircomm> 0600 root Version-Release number of selected component (if applicable): 0.99.3.0-3 How reproducible: always Steps to Reproduce: 1. 2. 3. Actual results: no sound Expected results: Additional info: Installing pam-0.99.3.0-3, sound doesn't work. $ alsamixer alsamixer: function snd_ctl_open failed for default: No such device
Yes, I can confirm this problem with pam-0.99.3.0-3 . After upgrading to rawhide-20060425 and pam-0.99.3.0-3, 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 /etc/security/console.perms.d/50-default.perms 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 .

Yup, commenting out that permission fixed the problem I described in BZ 189994 where /dev/pmu had the wrong ownership also.
Should be now fixed, also the pam_console_apply should now handle such lines gracefully, skipping them and not exiting.
