Incidentally all, 0.6.2 is out with a bugfix in permissions checking.

Besides the comments in autohandler and the install guide, none.  Soon,
I promise :)

BTW, the proper place for this use...@so... ... I'd
like to pollute the Mason list as little as possible with my bugs.

You might want to grab the new version I just put up (0.6.2) which fixes
the $sys->finished thing and makes the example permissions stuff look
better.  Answers below.

Yeppers.

And the <%doc> around it needs to be removed.  In fact, you don't need
either of those statements--they are redundant.  The default
check_permissions checks those no matter what.  And you're right about
the ->finished thing, I apparently didn't retest permissions hash after
changing %cleanup.  The new version fixes the error.

For the situation you described, this boolean checking won't help you
anyway, so you don't need to grab it yet.  Read on.

Since the default check_session only checks boolean, you'll have to
override check_permissions.  Search for %method check_permissions in
autohandler.  Remove the %doc around it.

For what you're looking for, check_permissions is your best bet.

Here's an example.  You can override this in different components to use
different levels.

<%method check_permissions>
<%perl>
my $user = $ARGS{-sys}{users}{$ARGS{-session}{_user_id}};
if($user->{UserLevel} < 5) {
        return 0;
}

return $m->call_method("session:check_permissions", %ARGS);
</%perl>
</%method>

You don't have to call session:check_permissions, but if you want to be
able to disable users using the "Cannot Do Anything" parameter it's a
good idea.
