[krbdev.mit.edu #5462] Vista no longer returns enctype 0 for unavailable session keys

[Jeffrey Altman via RT]

Confirmation has been received that Vista SP1 will include a hot fix
that re-enables access to session tickets for Administrator group member
accounts when running under UAC.

The cc_mslsa.c test for UAC will have to be modified to test for the SP1
version number.

Vista SP1 beta will be available to select testers within the next two
weeks.
