I have wrote the code in .net to access the MSCRM web service using organization and discovery services and its working properly for all the customer(online & onpremises) without any error.
Now, our new customer has to configured MSCRM(OnPremise) with Forefront TMG(Threat Management Gateway) to accept the credentials in this way because if you open the URL in web browser its open a Forefront TMG login screen and you can login fine into the CRM once you entered username and password into the Forefront TMG login screen.
But when we do login through web service using Discovery and Organization URL the credentials provided are not being accepted by Forefront TMG, but they work in a browser.
Request to please provide a solution how to access a MSCRM web service if the CRM is configured by Forefront TMG.
Thanks,
Ashish Manatkar
