Provides properties that describe the service credentials used for Windows authentication.
Assembly: System.ServiceModel (in System.ServiceModel.dll)
This class provides two settings.
You can use the AllowAnonymousLogons property to allow the anonymous logon of clients by setting it to true. You can then avoid disclosing the client's identity to the service by setting AllowedImpersonationLevel to Anonymous.
If the IncludeWindowsGroups property is set to true (the default setting), the service can determine the Windows groups to which the client belongs.
