The /lib64/libnss_sss.so.2 file is mislabeled # matchpathcon /lib64/libnss_sss.so.2 /lib64/libnss_sss.so.2 system_u:object_r:lib_t:s0 # Please run following command on your machine: # restorecon -Rv /lib64 Is this something that I have broken myself or is this something that needs to be fixed in selinux-policy? It looks like that you system is/was mislabeled, so there is no need to change it in selinux-policy. Are you able to reproduce it? Where does it come from? Beaker? Thank you. *** Bug 1388442 has been marked as a duplicate of this bug. *** Is it still relevant? Do you still see SELinux denials mentioned in comment#0? If not, we will close the bug because of mislableled filesystem on your side. Mislabeled files can be repaired via restorecon -Rv ... We're going to close this bug as WONTFIX because * of limited capacity of selinux-policy developers * the bug is related to EPEL component or 3rd party SW only * the bug appears in unsupported configuration We believe this bug can be fixed via a local policy module.
