The hint was to the AFS developers, that it is time, and some of us
use KDCs that are not modifiable.

Yes you can but then you have a local mod, and eventially AFS will
add the code to support k5 principals.

As Jeff said, aklog -524 would work or if you are still using
gssklog, the gssklogd has a mapping that would also work :-)
(No new work is being done on gssklog.)

  You other fix, use single valued principals might be the best bet.
