Description graf.drakul 2011-05-28 08:49:05 UTC
SELinux is preventing /usr/sbin/pcscd from using the 'sys_admin' capabilities.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that pcscd should have the sys_admin capability by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep pcscd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Dominick Grift 2011-05-28 10:32:40 UTC
Can you reproduce this?

Comment 2 Miroslav Grepl 2011-05-30 09:10:17 UTC
Could you try to turn on full auditing

# auditctl -w /etc/shadow -p w

Recreate AVC and then execute

# ausearch -m avc -ts recent
