Thanks for taking a crack at this. It has some number of problems, as is:
- It doesn't work on Solaris, because "-lkrb5 -lk5crypto", etc. aren't
getting added to $LIBS in the case where you build without krb4.
- It doesn't touch any of the non-client programs, which have krb4
dependencies of their own.
I believe I now have a working set of patches that address all of the
krb4 dependencies in the whole tree, which builds cleanly but is as yet
untested. I need to test the moirad and the reg_svr and then I'll feel
more comfortable checking this in.
