privacyIDEA is an authentication system that should suite your needs.
So it makes sense, that we ask you, what you need! Of course there is the community forum and the github repository, where you could write questions and issues. I know that it is sometimes easier to click answers.
This is why we started a privacyIDEA User Survey.
Thanks a lot for your Feedback!
