Update: I was able to limit this following the article below:
I was given the go ahead to purchase the enterprise license for Pritunl finally and have setup Azure SSO. I have searched quite a bit on this and cannot quite narrow down a way to do this.
Is there a way to limit the scope of who can sign in from our Azure tenant? Such as limit it to a group? Currently anyone who knows the URL could sign in from our tenant, I would like to keep that from happening.
Edit: I believe I might have found my answer right after posting this. Limiting access to the azure app (registration) that was created.
