What pre-requisite services/subscriptions do I need to get to that point?
Right now, we have Azure AD Connect. Can that be used to authenticate users' access to the network shares of Azure Files?
I had to setup an Azure subscription first to access storage services. The azure subscription did not show pricing because it was a trial subscription. I did not know whether it would be per user subscription or not.
Azure Files supports identity-based authentication for Windows file shares over Server Message Block (SMB) using the Kerberos authentication protocol through the following three methods:
For your use case where you want to use Azure AD Connect, you need to go with Azure AD Kerberos for Hybrid User Identities. You can find more information here- https://learn.microsoft.com/en-us/azure/storage/files/storage-files-identity-auth-azure-active-directory-enable?tabs=azure-portal
Here are details regarding a subscription in Microsoft Cloud- https://learn.microsoft.com/en-us/microsoft-365/enterprise/subscriptions-licenses-accounts-and-tenants-for-microsoft-cloud-offerings?view=o365-worldwide#subscriptions
Hope this helps. Please do let me know if you have further questions and I will be glad to assist you further. Thank you!
