The proNEXT identity provider 3 is a further development of the proNEXT IdP based on Keycloak. The extensive functionality of the previous IdP will only be gradually incorporated into Keycloak. In the first version only the login with user name and password as well as with the german identity card is supported. Keycloak itself offers a very extensive documentation, which is referred to here again and again.
The proNEXT identity provider (proNEXT IdP) is an authentication component with single sign on technology. By means of the proNEXT IdP it is possible to provide a central authentication possibility which can be accessed from different specialized applications. By default, the proNEXT IdP offers a login via user name and password. However, this functionality can be extended so that, for example, the new german ID card or SSL client certificates can also be used. The proNEXT IdP is multi client capable, so that specific authentication options can be configured for each client.
Both the proNEXT IdP and the service providers accessing it must be time synchronized via an NTP server. This should usually be a public time server. If all components have access to a local NTP service, a local server can also be used.
