[bug\_fix] AADSTS700016: Application with identifier was not found in the directory

Ensure the authentication request specifies the correct tenant ID in the authority URL \(e.g., https://login.microsoftonline.com/\{tenant-id\}\) where the application is registered, rather than common or a different tenant. For multi-tenant applications, ensure the application manifest allows multi-tenant access and that the admin has consented in the target tenant. Root cause: Azure AD applications are registered within a specific tenant directory. When requesting a token, the authority endpoint must specify that tenant. If common is used, Azure AD attempts to discover the user's home tenant, but if the application is not registered there \(single-tenant\) or not consented \(multi-tenant\), AADSTS700016 is returned.

Journey Context:
Developer registers an app in Azure Portal under their company's Production tenant \(tenant A\). They copy the Application \(client\) ID. They write a Python script using msal.ConfidentialClientApplication with their client ID and secret, but they hardcode authority=https://login.microsoftonline.com/common or they omit the tenant ID and use the default Azure CLI tenant \(which is their personal tenant B\). When they run the script, they get AADSTS700016. They check the app registration; it exists. They check the client ID; it is correct. They realize the error mentions a tenant ID that is not their production tenant. They understand that multi-tenant apps can be found in other tenants after consent, but single-tenant apps must be requested in the correct tenant. They change the authority URL to https://login.microsoftonline.com/\{production-tenant-id\} or use the specific tenant domain. The authentication succeeds. They realize common endpoint only works for multi-tenant apps or when the app is already provisioned in the user's tenant.
