Remarks

When this property is true, it effectively bypasses an important security feature in OPC Unified Architecture. Use this value only for testing and development purposes, or if your application does not require the server certificate check.

In order to obtain or modify this parameter for server instance certificates, access the UAClientServerEngineParameters.CertificateAcceptancePolicy property of EasyUASharedParameters.EngineParameters property of OpcLabs.EasyOpc.UA.EasyUAClientCore.SharedParameters. Alternatively, you can override the certificate acceptance policy for a specific endpoint by setting it to a non-null value in OpcLabs.EasyOpc.UA.UAEndpointDescriptor.CertificateAcceptancePolicy.

In order to obtain or modify this parameter for HTTPS certificates, access the UAClientEngineParameters.HttpsCertificateAcceptancePolicy property of EasyUASharedParameters.EngineParameters property of OpcLabs.EasyOpc.UA.EasyUAClientCore.SharedParameters.

This method or property does not throw any exceptions, aside from execution exceptions such as System.Threading.ThreadAbortException or System.OutOfMemoryException.

Requirements
