PrincipalPolicy Enumeration

Specifies how principal and identity objects should be created for an application domain. The default is UnauthenticatedPrincipal.

Namespace:  System.Security.Principal
Assembly:  mscorlib (in mscorlib.dll)

[SerializableAttribute]
[ComVisibleAttribute(true)]
public enum class PrincipalPolicy

Member nameDescription
NoPrincipalNo principal or identity objects should be created.
UnauthenticatedPrincipalPrincipal and identity objects for the unauthenticated entity should be created. An unauthenticated entity has Name set to the empty string ("") and IsAuthenticated set to false.
WindowsPrincipalPrincipal and identity objects that reflect the operating system token associated with the current execution thread should be created, and the associated operating system groups should be mapped into roles.

For performance reasons, the default principal and identity objects are not created until they are needed. If a principal is explicitly added to the current thread, a default principal is not created and the principal policy setting is ignored.

A trusted host can override the default principal policy by specifying another of these values using the SetPrincipalPolicy method of an AppDomain.
