Description of problem: SELinux is preventing /usr/bin/perl from open access on the file /etc/shadow. ***** Plugin catchall (100. confidence) suggests *************************** If you believe that perl should be allowed open access on the shadow file 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 BackupPC_Admin. /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp WARNING: Policy would be downgraded from version 27 to 26. WARNING: Policy would be downgraded from version 27 to 26.
