Hmmm, yeah, we don't have a -e argument for specifying a list of enctypes (or, rather, keysalttype). Anyways, you can set the [kadmin] section default_keys parameter to a list of keysalttypes like so: [kadmin] default_keys = aes256-cts-hmac-sha1-96:pw-salt default_keys = des3-cbc-sha1:pw-salt default_keys = arcfour-hmac-md5:pw-salt (That's the baked-in default list, FYI. We should probably drop des3 and arcfour and add aes128.) Nico --
