You can also fall back to basic_auth and even mod_auth_ldap I guess.
It's basically a matter of evaluating if you can live with letting other
services see the user's password or not.

In future we want to add auth mechanisms that do not necessarily depend
on Kerberos and will not expose the user password to random services,
like OpenID, Oath etc.. but we are not there yet.
