rails 3.2 subdomains and devise

Question

I have an application where users can log in to their firms subdomain.

I use devise. And this code redirects the user form the root domain to the subdomain.

def after_sign_in_path_for(resource_or_scope)
  scope = Devise::Mapping.find_scope!(resource_or_scope)
  subdomain_name = current_user.firm.subdomain
  if current_subdomain.nil?
    # logout of root domain and login by token to subdomain
    token =  Devise.friendly_token
    current_user.loginable_token = token
    current_user.save
    sign_out(current_user)
    flash[:notice] = nil
    home_path = valid_user_url(token, :subdomain => subdomain_name)
    return home_path
  else
    if subdomain_name != current_subdomain.name
      # user not part of current_subdomain
      sign_out(current_user)
      flash[:notice] = nil
      flash[:alert] = "Sorry, invalid user or password for subdomain"
    end
  end
  super
end

It works super in chrome, firefox, opera and safari, but it does not work in IE9. I do not get any error messages. Form the log i see that the user gets sigend in and when the user get redirected to the home page he/she is unauthorized. Has anyone an idea on what is going on? Form the log.

If you are going across subdomain it may be better to simply change your session cookie to be cross-domain.

Editing the session-store.rb file in initializers does this.

Babyreveal::Application.config.session_store :cookie_store,
key: '_babyreveal_session',
:domain => ".mybabyreveal.com"

Notice the . prefix on the domain attribtue. This allows this cookie to be accessible across subdomains and the application should maintain it's session across subdomains. May not be 100% what you are looking for but it should get you going in the right direction.
