@v-xianya I'm a bit confused here. In your repro steps you copy a direct link to a blob container, which means you already have access to a blob container. Why, then, would you expect the direct link to cause an error when attaching? If you didn't have access, you wouldn't be able to see the container to create a direct link in the first place...

@craxal If I paste the blob URL and connect via the Connect dialog using Sign in with OAuth, an authentication error is shown. Therefore, I expected the same behavior when connecting via Direct Link, since no RBAC role has been assigned to my account.
