i will take a look at exactly how condor locates the ticket for the client to
use, but i am guessing you are out of luck on windows at present. we will
probably either need to add some code to extract the ticket from the secure
LSA area (or find the proper windows API to access it).
kerb support was definitely added with only UNIX in mind. it was tested
against an AD server, and quite a while ago i believe it was tested on
windows using a keytab file, but never using windows' native key storage.

like i said, we the condor team will take a closer look at it, and if it is
not currently possible we'll add it to the list for the 7.3 series.
