SAP to CRM Dynamics Authentication

Posted on by Community Member

Hello,

I am not an CRM expert at all, I only have knowledge on the middleware SAP PI.

We have a project where SAP PI needs to connect to the CRM Dynamics System to Post some data via SOAP Protocol.

The URL the CRM Dynamics people gave to us looks like following: http://abc.com/xxxxx/XRMServices/2011/Organization.svc/web

Unfortunately we are not able to authenticate to this CRM Service.

We tried using NTLMv1 (NTLMv2 is not supported by our middleware) but we are getting HTTP 401 Unauthorized. To be honest we dont have any experiences in setting up NTLM connections. Usually we use Basic Auth for SOAP connections.

Now I am hoping to get some help from the CRM Experts in this Community.

Is it possible to access CRM Dynamics Webservices via basic auth? If yes, how? Which settings are needed on CRM System? Which on IIS? Using Basic Auth would be our prefered solution.

Thanks a lot.

RE: SAP to CRM Dynamics Authentication

Hi - I have been part of many SAP CRM integrations. PI is not able to authenticate CRM web service (I have seen so far). Also, the CRM service doesn't expose methods in its definition e.g. create/update etc which could be readily used by PI. What we do is we create a custom service - create methods for the operations which we want to do from PI. CRM authentication is done with in this service and this service is authenticated via basic auth to PI. Please let me know if you need more help around it if this is not already done.
