Experience has shown that it was a mistake to fail AP-REQ verification
based on failure to verify the signature of PAC authdata contained in
the ticket. We've had two rounds of interoperability issues with the
hmac-md5 checksum code, an interoperability issue OSX generating
unsigned PACs, and another problem where PACs are copied by older KDCs
from a cross-realm TGT into the service ticket. If a PAC signature
cannot be verified, just don't mark it as verified and continue on
with the AP exchange.
