An Azure service that offers file shares in the cloud.
Hi ,
Thanks for reaching out to Microsoft Q&A.
This is almost always not a wrong password issue but an identity mismatch with Kerberos. When mapping Azure file shares using AD or AAD DS, the credentials used for SMB auth must be the domain identity (for example, DOMAIN\username or ******@domain.com tied to AD), not the Microsoft account login used for the Azure portal. If you are using Azure Files with AD integration, ensure the storage account is domain-joined, your VM or machine is also domain-joined, and you are logged in with that domain user. Also verify SPN and Kerberos ticket using klist. If you are using AAD Kerberos (preview scenarios), make sure the device is Azure AD joined and you are using the correct UPN format. In short: portal login working does not mean SMB/Kerberos auth will work; align the identity type and domain join properly.
