Not able to connect to on-premise Dynamics 365 from within WCF Service hosted in IIS on same server

Hi,

I am facing issue while connecting to on-premise Dynamics 365 using CrmServiceClient(AD authentication) from WCF(http) service which is hosted on same app server. 

When I tried to debug it, serviceproxy is giving null value from the WCF service, however when I executed same connection method in console application, it is working fine.

Is there any additional configuration required in IIS for WCF web service so that it will consider AD authentication(windows)?
