Koumbit will be closing the OpenID service running on "id.koumbit.net" on the 1st of July 2017. From that moment on, you will no longer be able to log in to various sites with your Koumbit OpenID, including redmine.koumbit.net. If you do not currently use OpenID through id.koumbit.net, you do not need to take any action.
If you use OpenID, please ensure that you have alternative credentials to connect on the various sites and services you access before id.koumbit.net is shut down.
If you have any questions, or if the service closing date poses a problem for you, please contact us by e-mail at email@example.com.
Thank you, the Koumbit team
