Hi, I'm trying to integrate simple OpenID authentication through Google accounts. I'm using omniauth gem and on my local development system (Win7, ruby 1.8.7-p302, rails 2.3.8, omniauth 0.1.5) everything works nice.
The problem shows it's face when I deploy it to my hosting (HostGator). The app (mongrel) starts at port 12002 and through HostGator's cPanel it's configured to be rewritten from one of subdomains:
RewriteCond %{HTTP_HOST} ^subdomain.mycompany.com$ [OR]
RewriteCond %{HTTP_HOST} ^www.subdomain.mycompany.com$
RewriteRule ^(.*)$ "http\:\/\/127\.0\.0\.1\:12002\/$1" [P,L]
When browser goes /auth/open_id it's redirected to Google for authorization but it's return_to address is subdomain.mycompany.com:12002 which of course is incorrect because Apache doesn't listen on 12002. I've managed to monkey patch OmniAuth::Strategies::OpenID and Rack::OpenID so they assemble address without port BUT now on the final stage after user access confirmation if falls into:
Routing Error
No route matches "/403.shtml" with {:method=>:get}
I guess the problem is what my site's address is encoded (some kind of hash) at other authorization request parameter to avoid
