[krbdev.mit.edu #6491] Regression: pkinit causes assertion failure in 1.7 beta2

[Sam Hartman via RT]

Using a set of configuration files and database that works with pkinit with the 1.6.4 beta1 KKDC,
I get 
krb5kdc: ../../src/kdc/kdc_authdata.c:577: handle_authdata: Assertion `enc_tkt_reply->authorizatio
n_data == ((void *)0)' failed.                                                                   


when I try to request a pkinit authenticated ticket with 1.7 beta2 and
with the trunk.
