The obvious workaround here is to simply have an aklog which doesn't
perform the 524 step (if you have a modern openafs, it isn't necessary).
I haven't yet modified our aklog to do the necessary magic, but it's
not hard.  I believe that Jeff Altman said that KfW is going to go
that route as well.  When I get some free cycles, I'll add that
functionality to aklog.
