Unable to connect IFD CRM using Plugin Registration Tool

By | May 29, 2017

When we setup IFD configuration for Dynamic 365 it doesn’t always go smoothly.

Sometimes, after configuring IFD, the CRM connects through the web client, but it does not connect using Plugin Registration Tool.

The below message is displayed while connecting CRM using Plugin Registration Tool:

We have faced this issue many times and have found various solutions!

Below are three possible solutions to fix the issue. One of these has most often worked in resolving this issue.

In the three cases mentioned below, our window server version was “Windows Server 2012 R2”.

And ADFS version=“”.

Solution 1:

To change the port number you need to run the below command PowerShell.

Powershell command:

Set-ADFSProperties –nettcpport 809

This “/adfs/services/trust/13/username” endpoint in the Adfs was not enabled.

To enable, Open the adfs and go to Service>Endpoints, select the endpoint, right-click and enable it.

The endpoint is now enabled as seen in the screenshot below;

Solution 3:

The ActiveMexEndpoint in ADFS is as seen in the screenshot below;

set ActiveMexEndpoint = 'https://<adfs url>/adfs/services/trust/mex'
