My first reaction was: "yes, trivial, supply your own library
implementing getpwnam() which calls
radius, and you are done."
HOWEVER, you need rather special Radius server for that too.
In normal case the Radius server is used to AUTHENTICATE user,
that is, the Radius request contains username + password.
That latter the mailbox can't know.
All in all, Radius isn't good protocol for user profiling
(e.g. "yes, the user exists, here are some parameters"),
which things like mailbox need.
The underlying assumption in Radius AUTHENTICATE is that
there is a password which is verified before profile data
Having a custom server with a new type of request; say USERPROFILE,
could help the thing, but naturally such server must strictly limit
who can query it (like with Radius all the time.)
Perhaps LDAP would be better approach ?
