Suggested feature for rlm_detail: logging only a few specific users

[Bjørn Mork]

During debugging of production systems, I've often wished there was
some way to enable debugging only for specific users.

The attached patch (against 1.1.x CVS for now) extends rlm_detail with
an optional rlm_files compatible "usersfile" option.  It does not
change the behaviour for existing configurations.  

Usage example:

modules {
        ..
        detail debugusers {
                detailfile = "${logdir}/debuglog"
                usersfile = "${raddbdir}/users.debug"
        }
        ..
}
..
post-auth {
        Post-Auth-Type REJECT {
                debugusers
        }
}


Where users.debug contains a list of users to debug.  The syntax is
similar to users(5).  It can even contain check-items and DEFAULT
entries (which only makes sense if combined with check items), to
filter the logging even more.

I'm posting this here to get some feedback whether this is a good idea
or if I'm reimplementing something that already exists, or if this
should go into a separate module.

Comments?
