Repeater behind MS AppProxy without basic auth

[Prisma]

Hello Rudi,

I hope you're doing great! We use a rather old version, very stable, so no reason to post and ask things.

But now we would be interested to protect our repeater with SAML or openIDconnect with an IdP. But, as we found out, this was way too complicated (and would be much work for you). This is all is not necessary, because the used IdP is Microsoft. And Microsoft has its MS AppProxy. A very easy to install and very small Software for the target (repeater-)server. This Proxy enables modern authentication for legacy webservices. Therefore perfectly designed for repeater and others.

Now the question:
I'm curious if it would be possible to completely disable basic auth for repeater, because repeater would have his own doorkeeper sitting in front of it for authentication?

Entering an empty password would be no solution, because we need no username/password prompt at all. Or would changing the password to empty disable basic auth completely?
