Functions Can be used to Authenticate Directly with MSCRM Web services



1. On Premise MSCRM Authenication Function


public static IOrganizationService GetXrmService(string _crmUserName, string _crmURL, string _crmDomain, string _crmPassword)
        {

            Uri organizationUri = new Uri(_crmURL);
            ClientCredentials cCredentials = new ClientCredentials();
            cCredentials.UserName.UserName = string.Format("{0}\\{1}", _crmDomain, _crmUserName);
            cCredentials.UserName.Password = _crmPassword;
            OrganizationServiceProxy orgProxy = new OrganizationServiceProxy(organizationUri, null, cCredentials, null);
            orgProxy.EnableProxyTypes();
            _xrmService = (IOrganizationService)orgProxy;
            return _xrmService;
         

        }

2. Online Authenication function

       public static IOrganizationService GetOnlineXrmService(string _crmUserName, string _crmURL, string _crmDomain, string _crmPassword)
       {

           ClientCredentials credentials = new ClientCredentials();
           credentials.UserName.UserName = _crmUserName;
           credentials.UserName.Password = _crmPassword;
           credentials.Windows.ClientCredential = CredentialCache.DefaultNetworkCredentials;
           //  credentials.Windows.ClientCredential = new System.Net.NetworkCredential(_userId, _password, _domain);

           Uri organizationUri = new Uri(_crmURL);
           Uri homeRealmUri = null;
         

           using (_serviceProxy = new OrganizationServiceProxy(organizationUri, homeRealmUri, credentials, null))
           {
               _serviceProxy.ServiceConfiguration.CurrentServiceEndpoint.Behaviors.Add(new ProxyTypesBehavior());
               _xrmService = (IOrganizationService)_serviceProxy;
               _orgContext = new OrganizationServiceContext(_xrmService);
           }

           return _xrmService;

       }
