Bug 867415

sealert -l e6d2d369-5ac1-46e8-89f9-ab483923d21e
SELinux is preventing rpcbind from read access on the file /etc/passwd.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that rpcbind should be allowed read access on the passwd 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 rpcbind /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
