rails 3.2 subdomains and devise - ruby-on-rails

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.
