Yes, and that is expected. I suppose I have not been clear; you have two
different ways to make this work:
1. Extract a keytab for afs/cell with just DES, and nothing else, just
like you originally did (and add it to the KeyFile). Then get the
FreeIPA KDC and your client machine configured to use DES. If you have
not correctly configured these to let you use DES, then you get the
error you originally saw (-1765328370). If you've already set
allow_weak_crypto on the KDC and the client, then you may need to ask
the FreeIPA people for additional help.
2. Extract a keytab for afs/cell with non-DES enctypes, and install it
in rxkad.keytab. Follow the instructions I mentioned in
<http://openafs.org/pages/security/how-to-rekey.txt> to configure the
servers to use this keytab. If you have not configured the servers to do
this, then you will get errors such as "permission denied", as you have
So, follow one of those paths, and you should be able to get
authentication working. Your current setup I believe is following
neither of those approaches, and so it doesn't work. I would think
option 2 is easier, but that's up to you.
