I spent time testing out Keycloak Identity server for handling microservice authentication using OpenID connect. I was able to fully customise the freemarker theme to what I want.
It's got nice features too but somehow I still find it buggy, most annoying error is getting
"An error occurred, please login again through your application"
because the one time code is not valid on browser refresh.
I'm wondering if anyone is actually using it in production or it's just an Alpha release not ready for production yet ?
Current version: 2.5.0.Final
