Grant Entra B2B user access to Azure netapp file
I am currently delivering an Azure Virtual Desktop (AVD) RemoteApp solution to B2B users from an external organization. Due to performance requirements, the application needs to scale horizontally across multiple AVD session hosts. As a result, all session hosts require access to the same shared file storage.
The primary requirement is that access to the shared files must be fast and have very low latency. Based on my research, Azure NetApp Files appears to be the ideal solution.
However, it seems that Azure NetApp Files currently supports SMB access only through Active Directory Domain Services (AD DS), Microsoft Entra Domain Services, or Microsoft Entra Kerberos. From what I understand, this does not appear to work with B2B guest users who sign in with identities from an external organization.
Is there a supported way to grant B2B guest users access to a shared Azure NetApp Files SMB share? I don't mind using Microsoft Entra Domain Services or an Entra-joined environment if that's required—I just want to know whether this scenario is supported and, if so, what the recommended architecture would be. Thanks!
