:SELinux is preventing /usr/lib64/realmd/realmd from 'execute' accesses on the file /usr/bin/net.
:*****  Plugin leaks (86.2 confidence) suggests  ******************************
:If you want to ignore realmd trying to execute access the net file, because you believe it should not need this access.
:Then you should report this as a bug.  
:You can generate a local policy module to dontaudit this access.
:# grep /usr/lib64/realmd/realmd /var/log/audit/audit.log | audit2allow -D -M mypol
:# semodule -i mypol.pp
:*****  Plugin catchall (14.7 confidence) suggests  ***************************
:If you believe that realmd should be allowed execute access on the net file by default.
:Then you should report this as a bug.
:You can generate a local policy module to allow this access.
:allow this access for now by executing:
:# grep realmd /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

Comment 1 Daniel Walsh 2012-07-23 13:39:06 EDT
This looks like we need to back port realmd policy from Rawhide?
Comment 2 Stef Walter 2012-07-24 04:30:05 EDT
Sorry, this is a duplicate bug report. I must have been confused about which system I was on. realmd is only in rawhide.
