Fabric OS

This thing was a pain to get working, an example of the correct brocade av pairs is as follows:

        service = exec {
                brcd-role = admin
                brcd-AV-Pair1 = "homeLF=128;LFRoleList=admin:1,3,4;securityAdmin:5,6"
                brcd-AV-Pair2 = "chassisRole=admin"

As for do_auth, this completely breaks it.  I am thinking of adding an option to completely replace the pairs for weird/special things just like this.
