Version

4.20.0

Describe the bug

When using Cert based authentication, SNI auth flow is not working. I see in the code that x5c claim is not being passed in CertificateAppCredentials which results it not being passed (and used while calling AcquireTokenAsync) in MsalAppCredentials resulting in SNI auth breaking.

The sendX5c flag was being passed in the ADAL authenticator but got missed in MSAL one!

To Reproduce

Steps to reproduce the behavior:

  1. Deploy any sample bot service web app in Azure. The service should use an auto-renewed cert for authentication.
  2. Try sending notification request to the service. Auth flow would break with SNI auth issue
