There seems to be a problem with xscreensaver and pam_opensc-0.9.6-2. I'm using pam_opensc for required authentication on a system here, which works fine. The pam.d/system-auth has the following line: auth sufficient /lib/security/$ISA/pam_opensc.so This works for everything from login, to gdm. Only xscreensaver seems to have problems with this pam_module and won't unlock a screen: Jul 5 21:28:28 bofh xscreensaver(pam_opensc)[4103]: username [andreas] obtained Jul 5 21:28:28 bofh xscreensaver(pam_opensc)[4103]: get_certificate failed. Jul 5 21:28:28 bofh xscreensaver(pam_opensc)[4103]: Authentication failed for andreas at :0.0. Jul 5 21:28:32 bofh xscreensaver(pam_opensc)[4103]: username [root] obtained Jul 5 21:28:32 bofh xscreensaver(pam_opensc)[4103]: Authentication failed for root at :0.0. Jul 5 21:28:32 bofh xscreensaver[4103]: FAILED LOGIN 1 ON DISPLAY ":0.0", FOR "andreas" adding the parameters debug and audit to the pam_opensc module does unfortunately not result in further logging. On a related note: You should request pam_opensc being added to bugzilla as well. It's a single package.
Only source rpm names are Bugzilla components, and pam_opensc one is built from the opensc source rpm. Regarding the problem, I'm not able to test that right now, but a WAG: is there by chance traces of anything related in your /var/log/audit/audit.log?
Forgot to mention that in case this turns out to be a bug in pam_opensc, not the packaging, our chances of getting upstream help to fix it are kind of thin; it looks pretty strongly like they're dropping pam_opensc from the next release. The replacement will probably be pam_pkcs11 which is currently separately maintained by separate upstreams; I have a package of an oldish version of it, which I'll update and push to Extras if that's the way it'll be. And that'd be a bit painful upgrade :(
Nothing in the audit-log. Sucks...
This bug hasn't been updated in a long time and targets FE devel. Could you please check that it still occurs with current FE devel and update accordingly ? Thanks.
pam_opensc was dropped by upstream in opensc 0.10.0 (maps to FE5+). I gather pam_pkcs11 should be used nowadays instead.
