wcf - Is WindowsIdentity.Impersonate() necessary for WCF services?

Question

I am using a windows identity impersonation on a WCF service. Is it necessary to call identity.Impersonate() each time when I need impersonation, or can WCF do it for me? If it can, then what configuration should I specify?

Answer 1

您可以使用allowedImpoersonationLevel以下windows元素在客户端配置中进行设置：

<windows allowedImpersonationLevel="Identification/Impersonation/Delegation/Anonymous/None"
    allowNtlm="Boolean"/>
