Hi Folks,

Microsoft had recently announced on docs.microsoft.com that using WS-Trust authentication security protocol to connect to your Common Data Service had been deprecated.

So what does this mean??

Firstly you need to note that this only applies to client applications that connect to CDS.

It does not impact your custom plug-ins, workflow activities, or on-premises/IFD service connections.

Below are the places where you need to replace them…

If your code uses Username & Password for authenticating with Common Data Service or an application, you are likely using the WS-Trust security protocol.

• If you are using the OrganizationServiceProxy  class at all in your code, you are using WS-Trust.
• If you are using CrmServiceClient.OrganizationServiceProxy  in your code, you are using WS-Trust.

Check the following:

1. If your client applications using Microsoft.Xrm.Sdk.Client.OrganizationServiceProxy:

         Action Required:

        Replace all occurrences of the type OrganizationServiceProxy with  the IOrganizationService interface

      2.                            using CrmServiceClient with the “Office365” authentication type:

          Action Required:

          Switch over to using an OAuth based connection string, Note that LoginPrompt can be set to “never” to simulate the way that the Office 365 behavior worked. Please note that the App ID and Redirect URI should be created in AAD in your tenant.

Few points to note before we conclude:

• An update to Microsoft.CrmSdk.XrmTooling.CoreAssembly is available for download through NuGet package that includes auto redirect support. This library will redirect an authentication type of Office365 to OAuth.
• If you were not able to login even using OAuth, check if MultiFactor Authentication/conditional access is enabled, if so consider registering application user (Service Principal) in Azure Active Directory.
