OAuth pre-authentication in Azure Application Proxy
Currently pre-authentication in Azure Application Proxy implies user interacive logon to Azure AD. It would be great if one could choose an option to pre-authenticate as a annplication with a token in the same Azure AD tenant (and select an Oauth app which is regitered in the same tenant).
That's very useful when there is an external application/server accessing on-prem app via Azure Appliation Proxy would pre-authenticate with OAuth in Azure AD first and pass this token AAP.
Thanks for sharing your feedback. We will be further reviewing this feature and will update soon when we have more details.

This is mostly doable using the instructions found https://docs.microsoft.com/en-us/azure/active-directory/manage-apps/application-proxy-configure-native-client-application. I've hit some issues with it which I have raised a seperate UserVoice Item at https://feedback.azure.com/forums/169401-azure-active-directory/suggestions/38013307-enable-dedicated-app-proxy-authentication-header.
