    Hi,

    I have developed a c# windows application that connects with CRM to update some entities. When tested on premise, the application worked successfully, however when I deployed it at the actual live server for IFD it gives me a Sytem.InvalidOperationException: The user authentiction failed.

    Connection with CRM is done via the configuration file, and I am sure that the credentials are correct.

    <add name="Xrm" connectionString="Authentication Type=AD; Server=https://mycompany.mycompany.com:portnumber/; Domain=mydomain; Username=myusername; Password=mypassword" />

    Does anyone have any idea what the problem is? 

    Many Thanks!

    Hi guys,

    thanks a lot for your replies.

    I managed to solve this by removing the 'Domain' key value pair from the connection string in the config file, and instead included it in the username; i.e.

    FROM

    <add name="Xrm" connectionString="Authentication Type=AD; Server=https://mycompany.mycompany.com:portnumber/; Domain=mydomain; Username=myusername; Password=mypassword" />

    TO

    <add name="Xrm" connectionString="Server=https://mycompany.mycompany.com:portnumber/; Username=mydomain\myusername; Password=mypassword" />

    Thanks again!

    Make sure you're using the DLL's from the latest CRM SDK.

    How are you passing the credentials to CRM - i.e. what is the code that you use to instantiate and set the properties of the IOrganizationSerice (or a derived class) instance ?

    And are you using the sdk assemblies, or a service reference to connec to CRM ?

    If you are using the SDK assembly, this should do it:

    Uri serviceUrl = new System.Uri(string.Format("{0}{1}", ServerUrl, SERVICE_PATH));
                        ClientCredentials credentials = new ClientCredentials();
                        credentials.Windows.ClientCredential = CredentialCache.DefaultNetworkCredentials;
                        credentials.Windows.AllowedImpersonationLevel = System.Security.Principal.TokenImpersonationLevel.Impersonation;
                        if (!string.IsNullOrEmpty(UserLogin))
                        {
                            credentials.UserName.UserName = this.UserLogin;
                            credentials.UserName.Password = this.UserPassword;
                        }
                        service = new OrganizationServiceProxy(serviceUrl, null, credentials, null);
