I am using the domain access module https://drupal.org/project/domain for a city site. They have a lot of sub domains and these work fine for authentication. The users can go to any subdomain fire.#####city.gov/user and are able to login fine.
Now we are using the same access module to share content for another domain entirely ######lovecity.com. You can visit the login page ######lovecity.com/user and try to login. When you do it gives you an access denied. From what we can see the auth token only works for #####city.gov. Any help getting the authentication to work for both domains would be appreciated.
