Unfortunately, this is not a bug, but rather the behavior people seem
to expect.  Or at least the people with 64-bit systems don't want to
see this change because it would break existing ticket files.

The current claim is that the ticket-file format is dependent on
sizeof long and thus is dependent on the ABI of the library in
question.  If you wanted a sane authentication system you wouldn't be
using krb4.


There has been some discussion of adding support to read both formats
on all systems but I don't think code has been written.

This is a duplicate of another report with a much longer explanation
of the issue; I don't remember which report right now, but will try to
find it and link the two tickets.
