Have recently converted an application that connects to Dynamics CRM to use the new CRM Tooling connection method. It used an old method of connecting to CRM and I needed to update the connection method to support modern CRM Online.
No problem with this part,
IOrganizationService _crmService;
string connectionString = "....my crm connection string....";
CrmServiceClient service = new CrmServiceClient(connectionString);
_crmService = (IOrganizationService)service.OrganizationWebProxyClient != null ? (IOrganizationService)service.OrganizationWebProxyClient : (IOrganizationService)service.OrganizationServiceProxy;
This all works and can connect to IFD On-Premise deployments and CRM Online.
IFD is connecting with a string in this format:
AuthType=IFD;Url=crmorg.crmprovider.com/CRMORG;Username=myuser@domain.com;Password=MyPass;Domain=LegacyDomain;
It can also support MFA with CRM Online by registering an app in Azure and configuring a connection string in this format:
AuthType=OAuth;Url=yourcrm.crm.dynamics.com;AppId=APPID;RedirectUri=http://localhost;
What I am stuck on, is the format of the string on an IFD (On-Premise) deployment using On-Premise Microsoft MFA.
When I use the OAuth method with Azure AD, the application pops up a Microsoft Sign in Assistant that handles the user/pass and two factor request.
How do I construct a CRM Connection string that will do the same with an On-Premise CRM365 Deployment using the latest ADFS and MFA components from Microsoft? I know that the On-Premise installation challenges your user/pass (via ADFS) like the Microsoft Sign in Assistant, but how do I invoke that method of connecting when not working with CRM Online? Do i need to add an application to local ADFS? I can't seem to find any guide or documentation on this. There must be a way??!!
