This sounds about right.  BSD-flavored security is dependent on the
identity of the remote *host* (rather than some cryptographic
representation of a user identity).  One of the requirements is that
both forward and reverse DNS work for that IP <-> name.

We've also had some unsubstantiated reports of problems with dual-homed
Amanda servers, so if you run into further trouble after setting up
forward/reverse DNS, please speak up.
