No username or password in your app.</p> <p>Microsoft Entra authentication must be configured in two places: on the Azure SQL resource itself and inside the database. I only figured that out after spending quite a bit of time troubleshooting.</p> <p>My Web App&rsquo;s managed identity had <code>Contributor</code> on the SQL server, but connections still failed with &ldquo;Login failed for user&rdquo; until I ran <code>CREATE USER</code> inside the database. RBAC on the Azure resource is not the same as a database login.</p>
