Look at the Multi-user plugin, i think this may help. You will have to setup a re-direct by adding to your 'functions.php' file.
Try adding the plugin linked to your landing page, then find the sign-in function for the forum, copy to your functions.php [inside your theme folder - GS uses this file first] change the path so it can use the Mult-user.
I have not done this, ... so your on your own. Hope this helps.
