F5 APM as OAuth Authorization server and Resource server

Marvin, renaming the forward zone profile name with period(.) in the bigip.conf file and loading the config resolved the issue. Sounds crazy but worked.

**Before**
net dns-resolver /Application/oauth_dns {
forward-zones {
    oauth_forward_zone {
        nameservers {
            x.x.x.x:53 { }
        }
    }
}
route-domain /Common/0
use-ipv6 no
}

**After**
net dns-resolver /Application/oauth_dns {
forward-zones {
    . {
        nameservers {
            x.x.x.x:53 { }
        }
    }
}
route-domain /Common/0
use-ipv6 no
}
