Please see AzureAD/microsoft-authentication-library-for-go#467 for details.

Configuration of dSTS authority should be the similar to configuration of AAD or ADFS authority, i.e. MSAL does some internal parsing. I think we should not do it CIAM style (WIthOidcAuthority) because Azure SDK will not work with that.

Note: dSTS is single tenanted for all intents and purposes.
