Thanks for tracking down the relevant change.  I don't think we have a
user-accessible switch to turn off FAST TGS.  In principle you could
modify the ccache so that the client doesn't think the KDC supports
FAST, but that would involve writing code and probably isn't worth the
effort.  Alternatively, you could step through the code and

It can be tough to debug an interop problem, but Wireshark traces from
before and after the FAST TGS change could be useful.
