ticket: 6941
subject: Fix accidental KDC use of replay cache
target_version: 1.9.2
tags: pullup
r24464 (ticket #6804) intended to remove the KDC replay cache by
eliminating all of the USE_RCACHE code, but it had the unintended side
effect of causing krb5_rd_req_decoded to use the default server
rcache. Using this cache is much less efficient because it is opened
and re-read for each request.
Set appropriate flags on the auth context to disable replay cache use
for TGS requests altogether.
