   at Microsoft.Xrm.Sdk.Client.OrganizationServiceConfiguration.Authenticate(AuthenticationCredentials authenticationCredentials)

This my code:

 

public static IOrganizationService GetService()
{

    try
    {
        OrganizationServiceProxy _serviceProxy;

        string userName = "";
        string password = "";
        string domain = "";
        Uri serviceUri;


        serviceUri = new Uri(ConfigurationManager.AppSettings["URL"]);
        userName = ConfigurationManager.AppSettings["UserName"];
        password = ConfigurationManager.AppSettings["Password"];
        domain = ConfigurationManager.AppSettings["domain"];


        IServiceManagement<IOrganizationService> orgServiceManagement = ServiceConfigurationFactory.CreateManagement<IOrganizationService>(serviceUri);

        if (orgServiceManagement.AuthenticationType == AuthenticationProviderType.Federation)
        {
            // ADFS (IFD) Authentication
            ClientCredentials clientCred = new ClientCredentials();
            clientCred.UserName.UserName = userName;
            clientCred.UserName.Password = password;
            _serviceProxy = new OrganizationServiceProxy(orgServiceManagement, clientCred);
        }
        else if (orgServiceManagement.AuthenticationType == AuthenticationProviderType.OnlineFederation)
        {
            // Online authentication
            AuthenticationCredentials authCredentials = new AuthenticationCredentials();

            authCredentials.ClientCredentials.UserName.UserName = userName;
            authCredentials.ClientCredentials.UserName.Password = password;

            // Error getting here
            AuthenticationCredentials tokenCredentials = orgServiceManagement.Authenticate(authCredentials); 


            _serviceProxy = new OrganizationServiceProxy(orgServiceManagement, tokenCredentials.SecurityTokenResponse);
        }
        else
        {
            // On-Premise, non-IFD authentication
            ClientCredentials credentials = new ClientCredentials();
            credentials.Windows.ClientCredential = new NetworkCredential(userName, password, domain);
            _serviceProxy = new OrganizationServiceProxy(serviceUri, null, credentials, null);
        }

        _serviceProxy.EnableProxyTypes();


    }
    catch (Exception e)
    {

    }

    return (IOrganizationService)_serviceProxy;

}

    Are you sure that you are using correct O365 connection string :

    <add name="MyCRMServer" connectionString="AuthType=Office365;Username=jsmith@contoso.onmicrosoft.com; Password=passcode;Url=https://contoso.crm.dynamics.com&quot;/>  

    should be the connection string you should use (refer : msdn.microsoft.com/.../mt608573.aspx) for more options like using UI prompt to enter cred etc.

    Hi,

    You should use simplified connection, it's much easier and you will save a lot of time if you will have mutliple environments you want to connect to:
