I assume you just delete the kdc files in /var/lib somewhere before
recreating the database. But I'm not looking up the details right now,
and I don't think I've ever done the procedure you are performing :)

I'm not sure what exactly you're talking about here. There is only one
afs/* principal, the cell principal. The afs/cellname principal.

This is just what the error message says. Using -norandkey means you
extract existing keys into /tmp/afs.keytab, but using -e is for
specifying the enctypes for new keys to be written out. It doesn't make
sense to use both of them at the same time. You're either extracting
existing keys, or you're generating new keys and writing them to
And yeah, you probably want to use non-DES for the new principal.

Correct. You don't need to recreate any data or databases or whatever
for afs, just update some config files.

Unless you changed it, you can just move it back...
