AVD: The logon attempt failed

[IliaRud]

I encountered a strange behavior when authenticating.

AVD: Azure AD Auth, no Intune.

After granting permissions I cannot login and get "The logon attempt failed"

If I join clients computer to Azure AD it starts working.   (no MFA)

When I used in the past Azure Domain Services I did not come across such such "jokes".

Is anywhere a deep dive explanations of autherntication for different AVD scenarios?

@IliaRud If the AVD session host is Azure AD joined, add the custom RDP property "targetisaadjoined:i:1" to the host pool to allow connections from non-AAD-joined clients.  This is detailed in the authentication requirements at https://docs.microsoft.com/en-us/azure/virtual-desktop/deploy-azure-ad-joined-vm.
