Prompt Azure AD credentials while accessing container(set to private access level) using shared key.
When the access level of the container is set to "anonymous", sharing a URL of the file would allow users to download file. But, when the
access level is set to "private", an authorized request specifying date header is required. This requires extra steps and SAS keys expires.
Azure storage does not currently support prompting Azure AD credentials while attempting to access URL to download. Upon successful entry of credentials, users should be able to access the file. This feature allows using the same URL(as anonymous) to download the file and security is ensured using Azure AD authentication.
