I'm using Fedora 20 and CentOS 7 and have tried several places to place keytab files for Postfix. Each time I'm getting a denied message:

I see on the postfix_selinux man page that there is a postfix_keytab_t type, however, even if I use this, postfix is not able to read the credential file. Has anyone gotten this to work?

What AVC do you get with the default setup?

We will need to add additional rules.
