We already have a variety of authentication mechanisms that support
central management: LDAP, PAM, Kerberos, Radius. What other mechanisms
are people thinking about implementing using these hooks? Maybe there
are a bunch of them, in which case a hook system might be sensible, but
if there are only one or two plausible ones, we could also just make
them built in.
