The user is prompted for smart card PIN as expected
Due to insufficient SELinux policy rules, the `ppl_child` process, running in the `sssd_t` SELinux domain, was unable to manage the authentication cache and connect to Apache ports. Consequently, the system did not prompt the user for smart card PIN. The SELinux policy rules, provided by the _selinux-policy_ package, have been updated to allow this functionality. As a result, the user is prompted for smart card PIN as expected in the described situation.
