[krbdev.mit.edu #1006] [krbdev@mit.edu #1006]Correct solution

[Sam Hartman via RT]

In this bug Nico suggests that the KDC sort the etype info based on
what the client requested.  I actually think the client should sort
the returned etype info based on what it requested and should check to make sure the etype is supported as  it does this sort.

The KDC should not return etypes  that the client didn't request.
