I'm using Doorkeeper for my Rails app, and I'm trying to make so that when a user signs out from the doorkeeper provider, the user will automatically signs out from all apps. 

By default, when a user signs out from an app, he will still be signed in at the doorkeeper provider app.

This is my session controller from my Doorkeeper provider.

```
class SessionsController < ApplicationController
  def new
    redirect_to root_path if current_user
    session[:return_to] = params[:return_to] if params[:return_to]
  end

  def create
    user = User.find_by_email(params[:email])
    if user && user.authenticate(params[:password])
      session[:user_id] = user.id
      if session[:return_to]
        redirect_to session[:return_to]
        session[:return_to] = nil
      else
        redirect_to root_path

      end
    else
      flash.now.alert = "Email or password is invalid"
      render "new"
    end
  end

  def destroy
    session[:user_id] = nil
    flash[:alert] = "Sign Out successfully"
    redirect_to new_session_path
  end
end

```

This is my session controller from one of my app:

```
    class SessionsController < ApplicationController
  def create
    auth = request.env["omniauth.auth"]
    user = User.find_by_provider_and_uid(auth["provider"], auth["uid"]) || User.create_with_omniauth(auth)
    session[:user_id] = user.id
    session[:access_token] = auth["credentials"]["token"]
    redirect_to root_url
  end

  def destroy
    session[:user_id] = nil
    session[:access_token] = nil
    redirect_to root_url
  end
end

```

I wrote my own user authentication for the Doorkeeper provider app, but I used Devise for own of my app connected to my Doorkepeer provider app.

At the moment, when I sign out from my Doorkeeper app, I'm still signed in at my other app. So how do I make so that I sign out from Doorkeeper, and that will make me sign out from all apps as well?
