Gitlab's logout does not redirect to CAS logout

[tkaito]

Hi, I'm trying to use omniauth-cas3-1.1.3 with gitlab-8.14.4. I successfully logged in to gitlab via CAS, but when I logged out, gitlab des not redirect to CAS logout.

gitlab_rails['omniauth_providers'] = [
  {
    "name"=> "cas3",
    "label"=> "cas",
    "args"=> {
      "url"=> 'http://127.0.0.1:8000',
      "login_url"=> '/cas/login',
      "service_validate_url"=> '/cas/p3/serviceValidate',
      "logout_url"=> '/cas/logout',
    }
  }
]

Or should I use "on_single_sign_out"? But I don't know how to use it.

Same problem here

maybe you can change the source code at app/controllers/application_controller.rb, add the logout url to be the function after_sign_out_path_for.

def after_sign_out_path_for(resource) 'http://127.0.0.1:8000/cas/logout' end
