I suggested that the cache be bound to a user and the requesting IP
address, maintain only a volatile cache (in memory) per DC for a
configurable period of time (suggested 30 seconds as this feature mostly
serves to mitigate automatic authentication attempts from mis-behaving
applications with a cached password). This approach also removes the
minor attack-exposure increase that the n-2 mechanism provides.

I'll look into the hot fix designation, I researched my docs. on the
feature but I'm afraid none of them elude to anything specific. I'll
post back if I manage to dig anything up.
