KFW's "klist.exe -C"  won't list any afs service tickets if the internal
kauth krb4/udp implementation was used.

If you turn off "EnableKFW" then the MSLSA: ccache will not be used and
the "AllowTGTSessionKey" will not matter.  "AllowTGTSessionKey" is 
necessary for KFW to be able to obtain a TGT from the MSLSA: ccache and
copy it into a MIT CCAPI ccache.  (ms2mit.exe)

afscreds.exe will attempt to obtain an AFS token via the MSLSA: ccache
if it is available.

aklog.exe only tries to use the MSLSA: ccache if you have specified 
MSLSA: to be your default MIT krb5 ccache or set the environment 
variable KRB5CCNAME to MSLSA:.
