WebRequest.AuthenticationLevel Property

Gets or sets values indicating the level of authentication and impersonation used for this request.

Namespace:  System.Net
Assembly:  System (in System.dll)

member AuthenticationLevel : AuthenticationLevel with get, set

Property Value

Type: System.Net.Security.AuthenticationLevel
A bitwise combination of the AuthenticationLevel values. The default value is MutualAuthRequested.
In mutual authentication, both the client and server present credentials to establish their identity. The MutualAuthRequired and MutualAuthRequested values are relevant for Kerberos authentication. Kerberos authentication can be supported directly, or can be used if the Negotiate security protocol is used to select the actual security protocol. For more information about authentication protocols, see Internet Authentication.
To determine whether mutual authentication occurred, check the WebResponse.IsMutuallyAuthenticated property.
If you specify the MutualAuthRequired authentication flag value and mutual authentication does not occur, your application will receive an IOException with a ProtocolViolationException inner exception indicating that mutual authentication failed.
