+OpenID setup doesn't work out of the box.  The open id provider must be configured:
+
+* Authentication name: `keycloak`
+* OAuth2 Provider: `OpenID Connect`
+* Client key: `gitea`
+* Client secret: (copy from `../data/gitea/env.secrets`)
+* Discovery URL: https://login.hackerspace.zone/realms/hackerspace/.well-known/openid-configuration
