Hi,

I am new to Dynamics Environment. I am trying to connect to my Trial Instance of Dynamics 365 from .net Console Application.

I can login with my Username and Password from browser. But I can't login from application.

 private static string GetCrmService(string name)
        {
            IOrganizationService OrganizationService = null;
            try
            {
                ClientCredentials mycredentials = new ClientCredentials();
                mycredentials.UserName.UserName = "My UserName";
                mycredentials.UserName.Password = "My Password";
                ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
                OrganizationService = (IOrganizationService)new OrganizationServiceProxy(new Uri("My Organisation Service Api"), null, mycredentials, null);
                if (OrganizationService != null)
                {
                    Guid userId = ((WhoAmIResponse)OrganizationService.Execute(new WhoAmIRequest())).UserId;
                    if (userId.Equals(Guid.Empty))
                    {
                        Console.WriteLine("Connection can't be established");
                        return userId.ToString();
                    }
                    return "";
                }
                else
                {
                    Console.WriteLine("Connection Established Successfully");
                    return "";
                }
            }
            catch(Exception ex)
            {
                Console.WriteLine("Exception caught:" + ex.Message);
                Console.WriteLine("Inner Exception:" + ex.InnerException+"\nMesssage:"+ex.InnerException.Message);
                return "";
            }
        }

It shows Authentication Error. But I am using same Username and Password for Browser login. That is fine.

Can someone help me out

We found Azure AD Conditional Access could cause this as well, details in article linked below

Hi guys,

I just figured out problem is not with Dynamics but rather with mail Id I used for trial instance. Its my organization Id and my organization firewall preventing me from accessing application.

I created a new instance with different Id and its working perfectly.

Thanks all for your reply. All your responses were very helpful since I am a beginner.

Hi sulthan,

It's strange as I could successfully run the above function. I found one old post which shares the similar issue which is due to the incorrect timezone or if same timezone but different 5 min.

[View:https://community.dynamics.com/crm/f/117/t/204264:750:50]

You could check the timezone in personal options.

Hope the above would help.

Hi,

When you say the user credentials worked fine in browser, did you type in the user credentials or it logged you in automatically (saved password). If you have your credential stored/ saved in browser then browser will let you in even if your credentials I changed for sometime.

Try inprivate browser to login and confirm if you are able to login. Alternatively you can try login into any of the other tools like plugin registration, Xrm toolbox etc to isolate if the issue is related to credentials or your app. If you are able to login to other tools then it must be something with your app. Try different .net framework in this case.

If you are unable to login to other tools then it must be your credentials, and you should use correct credentials.

Hope this helps.

Hi Gong,

Thanks for reply. But that exception still comes.

When I tried to debug it , I found that this error comes when I try to get Response from execute method.

Can you please provide any help regarding that?

Hi Partner,

Your logic is something wrong as 'Connection Established Successfully' is due to userid could be successfully validated.

In addition, why the connection is built successfully when the OrganizationService = null? The logic is completely in reverse.

Change the If Logic as follow:

if (OrganizationService != null)
                {
                    Guid userId = ((WhoAmIResponse)OrganizationService.Execute(new WhoAmIRequest())).UserId;
                    if (userId != Guid.Empty)
                    {
                        Console.WriteLine("Connection Established Successfully");
                        return userId.ToString();
                    }
                    return "";
                }
                else
                {
                    Console.WriteLine("Failed to Established Connection!!!");
                    return "";
                }

Then you could successfully access your Organization Service Endpoint Address.

Hope the above would help.
