If all you are doing is wanting to use the same form for both user login and
user registration, it should be fairly straightforward. In your Auth
subclass, you would set the $mode to 'reg', setup auth_registerform() to
display the registration form (if this is the same as the normal login form,
you could probably just have it in turn call auth_loginform() to display
it), then you would set up auth_doregister() to first check to see if the
login name and password provided are valid, and if they aren't, then go
ahead and register the user in the system.

The code might look something like this.

ExampleAuth extends Auth {
    //...other settings variables go here
    var $mode = 'reg';

    function auth_registerform() {
        //code to display the registration form goes here; usually you can
just copy
        //and modify the code for auth_loginform() to suit your purposes.
    }

    function auth_doregister()
        //validate the login... you can probably use the existing
        //auth_validatelogin to do this
        if (!$uid = $this->auth_validatelogin()) {
            //A valid uid wasn't returned, so go ahead and register the
user.
            //...registration code goes here; be sure to set the uid and
perms for the new
            //user
            ...
            $uid = (something);
            $this->auth['perm'] = 'user';
        }
        return $uid; //return the uid to PHPlib so that it recognizes the
user as valid.
    }

    function auth_validatelogin() {
        //Code to login a user goes here
        return $uid;
    }

    ...
}

I have also found in working with the Auth class that this flow chart has
helped me immensely:

P.D. Si necesita algu'n explanacio'n en espan~ol, puedo intentar clarificar
lo que dije. Quizas tendre' que buscar mi diccionario. :)
