Hello,
So far my research stop at Microsoft:
- To login to WVD App (web/desktop) can be done using Passwordless
- Apps, that are published from on-premise AD domain, ask for domain credentials
- The authentication traffic goes and ends in "rdweb.wvd.microsoft.com", but this is not our domain, therefore we receive an authentication prompt
The solution from Microsoft to deploy WHFB works, but it requires a VPN connection from my client's PC to the domain, but we don't have VPN and don't want to deploy it.
