Thanks for the pointer. The attacks in that document aren't relevant to rxgk, because we don't use any information derived from the DNS in determining the acceptor identity.

rxgk defines the GSSAPI acceptor as being r...@_afs.<cellname>. For Kerberos sites, this has the advantage if their cellname is a DNS name, then their existing domain->realm mapping rules should take care of determining the realm of the principal.
