App proxy external URL access

[stromnessian]

Hi

If a user has access to an on-prem app that is published via App Proxy using passthrough authentication, can the user access the external URL if they are not assigned the app in Azure AD?

Many thanks

Hi @stromnessian 

Not sure if you've already gotten your answer but I do have an App Proxy with passthrough authentication that is operational even if they are not assigned the app in Azure AD. My understanding is that:

- you would only need to assign the app in Azure AD if you choose your App Proxy Pre Authentication method to "Azure Active Directory"

- passthrough authentication bypasses Azure AD

I've also stumbled upon this really helpful video to understand how both app proxy authentications work: https://www.youtube.com/watch?v=BXHbYSRSpic

Good luck!
