    <p>I have a problem with the UserIdentity(user, password) constructor. My password is 4 characters long. When the password arrives at the server it is 36 characters long. The first 4 characters are my password - the rest is random garbage.</p> <p>The Opc.Ua.Client.dll &amp; Opc.Ua.Core.dll have version 1.0.238.1.</p> <p>What is causing this and what can I do to send the password correctly?</p> <p><strong>UPDATE</strong></p> <pre><code>ApplicationConfiguration configuration = Helpers.CreateClientConfiguration(); X509Certificate2 clientCertificate = configuration.SecurityConfiguration.ApplicationCertificate.Find(); configuration.CertificateValidator.CertificateValidation += new CertificateValidationEventHandler(CertificateValidator_CertificateValidation); EndpointDescription endpointDescription = Helpers.CreateEndpointDescription(Url); EndpointConfiguration endpointConfiguration = EndpointConfiguration.Create(configuration); endpointConfiguration.OperationTimeout = 300000; endpointConfiguration.UseBinaryEncoding = true; ConfiguredEndpoint endpoint = new ConfiguredEndpoint(null, endpointDescription, endpointConfiguration); BindingFactory bindingFactory = BindingFactory.Create(configuration); if (endpoint.UpdateBeforeConnect) { endpoint.UpdateFromServer(bindingFactory); endpointDescription = endpoint.Description; endpointConfiguration = endpoint.Configuration; } SessionChannel channel = SessionChannel.Create( configuration, endpointDescription, endpointConfiguration, bindingFactory, clientCertificate, null); m_Session = new Session(channel, configuration, endpoint); m_Session.ReturnDiagnostics = DiagnosticsMasks.All; m_Session.KeepAlive += new KeepAliveEventHandler(Session_KeepAlive); m_Session.Notification += new NotificationEventHandler(m_Session_Notification); UserIdentity identity; if (userName == null || userName.Length == 0) { identity = new UserIdentity(); } else { identity = new UserIdentity(userName, password); } m_Session.Open("ATF UA client", identity); log.Debug("Connect ok"); </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
