Is it possible to authenticate the user token against multiple 'Client Id' from the same tenant ? Here is the configuration which uses the same 'ValidAudience' for Client Id.
app.UseWindowsAzureActiveDirectoryBearerAuthentication(
new WindowsAzureActiveDirectoryBearerAuthenticationOptions
{
TokenValidationParameters = new TokenValidationParameters { ValidAudience = B2b_ClientId },
Tenant = B2b_Tenant,
Provider = new OAuthBearerAuthenticationProvider
{
}
});
