Should httpd be accessing this file? If so, how would I set up that configuration? It seems that if this type of access is necessary, a boolean would be in place.



Yes it should have the ability to read it.  The only reason there is a
type on this file is for database admins to be able to manage it.

So  will update policy to allow http to read the file.

   Humm.. /me puzzled
Could someone please explain why would the web server (aka httpd) need read access to the configuration of the MySQL server ? I've seen quite a few servers in place and never felt the need to crossmix those two servers daemons with their config files. I've also thought that httpd reads/uses /etc/httpd/*, mysqld uses /etc/my.cnf and httpd + DB implies httpd talking to mysqld .
