Using Multi Factor authentication with Xrm.Tooling.CrmConnectControl

(0) ShareShare
ReportReport
Posted on by Community Member

Hello all,

I have tried logging in to an Multi Factor Authentification (MFA) enabled 365 Online environment using both the Xrm.Tooling.CrmConnectControl from the CRM SDK Template (added to existing project) downloadable at https://marketplace.visualstudio.com/items?itemName=DynamicsCRMPG.MicrosoftDynamicsCRMSDKTemplates and the one provided in the lastest SDK SampleCode called QuickStartXRMToolingWPFClient. I have not successfully logged into the MFA environment in either case. Ofcourse all the non-MFA environments I have tried to log into works as intended using both the described solutions.

In Plugin Registration Tool v.8.2.0.8411 it is possible to log into an MFA-enabled environment by leaving both User Name and Password blank when targeting Deployment Type Office 365. However when using the CrmConnectControl from the Template/SDK leaving User Name and Password blank results in the error message "A user name is required." alternatively "A password is required.". 

Does anyone know if there is a way to use the Xrm.Tooling.CrmConnectControl to authenticate to a MFA environment in the same way as it is done in the Plugin Registration Tool?

Best Regards,

Filip Sannerud

    The release notes of www.nuget.org/.../Microsoft.CrmSdk.XrmTooling.CoreAssembly

    states that Xrm.Tooling should support MFA.

    Check your references if you have the correct version.

    Hi

    for any body who is struggling to connect old Console Application code with MFA Enabled CRM

    To Connect MFA Enabled Dynamics CRM with C# you just need to use App Password instead of your Password remaining every thing remains same as it was

                  string connectionString = GetServiceConfigurationfromAppCOnfig();

                 ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

                 CrmServiceClient conn = new Microsoft.Xrm.Tooling.Connector.CrmServiceClient(connectionString);                

                 _orgService = (IOrganizationService)conn.OrganizationWebProxyClient != null ? (IOrganizationService)conn.OrganizationWebProxyClient : (IOrganizationService)conn.OrganizationServiceProxy;

                 WhoAmIResponse whoAmIResponse = (WhoAmIResponse)_orgService.Execute(new WhoAmIRequest());

    Follow the Steps to generate App password
