The first one above is with an AFS service ticket while the second one
does not have an AFS service ticket.  The possibly more useful difference
without that change is:

-rw-------    1 rra      root          132 Feb  3 19:35 /tmp/tkt11857
-rw-------    1 rra      root          136 Feb  3 19:36 /tmp/tkt11857

suspiciously four bytes too long.  Quanah, you may want to make sure that
in the process of fixing the uint64_t thing you didn't use a long long
somewhere that you didn't want to, or a long somewhere that an int should
be, but it might be another issue.

And by aklog, we mean the KTH afslog program.
