Due to a project I was given to work on, I had need of the memory
ccache. However, it appears it needs to be explicitly registered
by any application wanting to use it.
I made a change to lib/krb5/ccache/ccbase.c to construct a linked list
of methods (created at compile-time, krb5_cc_register() can still append
to this list) with one of (fcc, scc) first followed by the mcc memory
ccache.
It seems this might be one more item to get into the MIT tree. Here are
the diffs from Cygnus's code:
