Troubleshoot multi-tenant authentication

This article provides guidance on dealing with issues encountered in a multi-tenant context.

When you use credentials in a multi-tenant context, you can optionally try/catch for ClientAuthenticationException. The following table shows the errors that this exception indicates, and methods of mitigation:

Error message	Description	Mitigation
The current credential is not configured to acquire tokens for tenant <tenant-ID>	The application must configure the credential to allow acquiring tokens from the requested tenant.	Add the requested tenant ID to additionallyAllowedTenants on the credential builder, or add "*" to additionallyAllowedTenants to allow acquiring tokens for any tenant. This exception was added as part of a breaking change to multi-tenant authentication in version 1.6.0. Users experiencing this error after upgrading can find information about the change and migration in BREAKING_CHANGES.md
