@batamig - This PR fixes a typo (Azure Access Directory -> Azure Active Directory), but this product has been rebranded as Microsoft Entra ID. Let us know if you'd like us to make that update here.

IMPORTANT: When the changes are ready for publication, add a #sign-off comment to signal that the PR is ready for the review team to merge.
