Regarding Retiring WS-Trust authentication protocol for connecting to Dataverse

[sanket1828]

Hello ,

Hope You are doing well.

I am one of the developers working on Microsoft technologies.

I have a query about the WS-Trust authentication protocol which is going to be retired soon.

I am using below different approaches for the Dynamics CRM authentication.

Online Authentication

                var conn = new CrmServiceClient($@"AuthType=ClientSecret;url={organizationUri};ClientId={clientId};ClientSecret={clientSecret}");

                conn.OrganizationWebProxyClient.InnerChannel.OperationTimeout = new TimeSpan(0, Convert.ToInt16(ConfigurationManager.AppSettings["MDC_ServiceTimeOut"]), 0);
                return conn.OrganizationWebProxyClient != null ? conn.OrganizationWebProxyClient : (IOrganizationService)conn.OrganizationServiceProxy;

OnPremise Authentication

              String connstr = "authtype=Office365;Url=" + _OrganizationUri + ";Domain=" + _domain + ";Username=" + _userName + ";Password=" + _password + "";
              ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
              CrmServiceClient conn = new CrmServiceClient(connstr);
               if (conn.IsReady)
               {
                    service = conn.OrganizationWebProxyClient != null ? (IOrganizationService)conn.OrganizationWebProxyClient : (IOrganizationService)conn.OrganizationServiceProxy;
               }

So for the above, all two approaches do I need to make any changes?

Please guide me on this.

Your help would be really appreciated.

Awaiting Your positive reply.

Hello,

I'm not sure why do you need proxy at all. I use the following code in my apps that works transparently for both Online and On-Prem:

var conn = new CrmServiceClient("Your Valid Connection String");

if (!conn.IsReady)
{
//handle the connection issue here
}

//use conn object here

MSFT published a page on just this topic to help guide you away from WSTrust and the OrganizationServiceProxy class. I think you'll find the answers you're looking for here.

This works fine. I have only concern that how We can authenticate the user which is not on cloud and having port number with the organization URI. see below example URL

"https://crm.organization.com:444/.

I am trying to to using oath type "Office365". but not getting succeeded. 

Please advice on this.
