You spoof DNS returns and thereby change your local UID.  Not necessarily
a nasty attack assuming that the system doesn't honor UIDs outside your
user UID space and you use AFS exclusively, but it might still let people
do nasty things in /tmp and the like.

LDAP is considerably easier to secure; for one, you can easily use SSL
with it, and you can go further and use GSSAPI authentication if you need
real protection.

DNSSEC doesn't actually exist in a deployable form for real-world
applications even according to the people who designed it, but that's
another argument.
