Description of problem: SSSD's component sssd_ssh generates SELinux AVCs as it tried to name_connect to port 80 to OCSP responder and gets denied access. Version-Release number of selected component (if applicable): selinux-policy-3.13.1-158.15.fc23.noarch selinux-policy-targeted-3.13.1-158.15.fc23.noarch sssd-1.13.4-3.fc23.x86_64 How reproducible: User needs to have user certificate in FreeIPA, then try to SSH connect to the system with pubkey authentication. Steps to Reproduce: 1. Create user in FreeIPA, create userCertificate for the user 2. Let that user SSH into FreeIPA joined host with pubkey authentication 3. Observe AVCs in /var/log/audit/audit.log Actual results: type=AVC msg=audit(1466495870.659:9237): avc: denied { name_connect } for pid=27415 comm="sssd_ssh" dest=80 scontext=system_u:system_r:sssd_t:s0 tcontext=system_u:object_r:http_port_t:s0 tclass=tcp_socket permissive=0 type=AVC msg=audit(1466495870.660:9238): avc: denied { name_connect } for pid=27415 comm="sssd_ssh" dest=80 scontext=system_u:system_r:sssd_t:s0 tcontext=system_u:object_r:http_port_t:s0 tclass=tcp_socket permissive=0 Expected results: No AVCs. Additional info: - In my case this causes for whole authentication to fail, cause there's also sss_ssh_authotizedkeys having errors, but as requested in https://www.redhat.com/archives/freeipa-users/2016-June/msg00351.html I'm opening bug to fix these AVCs - I was not able to observe this behaviour on RHEL/CentOS 7.2, only on Fedora 23, maybe because of probably newer SSSD, but still please consider backporting to RHEL/CentOS.
