Where can I get a tutorial or instruction how to implement my own OpenID and Oauth2 servers for authorizing my microservice? I use java app and microservice I want to put authorization to. Where can I get an example of this auth server and may be there existing ones in the internet?
Please check http://www.keycloak.org This is an open source authentication server by Red Hat. Tons of documentation, start from here:http://www.keycloak.org/documentation.html
