Unable to login to SMB share using User Principal Name in AAD DS environment

Question

I have set up an AAD DS environment to allow my users to login to our Azure File Shares over SMB. However, when attempting to login with their User Principal Name in the format of "@domain.com", the system is telling them their password is incorrect while the format "@ds.domain.org" does work. The AAD DS domain is set to "ds.domain.org" as "domain.com" is occupied by our website. Am I missing something in my setup?

Thanks for posting your question in the Microsoft Q&A forum.

Since the AAD DS domain is "ds.domain.org," users should use the UPN format "@ds.domain.org" to log in successfully. Using "@domain.com" won't work because it doesn't match the AAD DS domain.

You can consider setting up a custom domain in Azure AD that matches your AAD DS domain ("ds.domain.org") to allow users to log in with the format they are familiar with ("******@domain.com").
