SecurityTokenAuthenticator Class

Authenticates a security token.

Namespace:  System.IdentityModel.Selectors
Assembly:  System.IdentityModel (in System.IdentityModel.dll)

public ref class SecurityTokenAuthenticator abstract

The SecurityTokenAuthenticator class and the classes that derive from it authenticate security tokens. Typically, you would only derive a class directly from SecurityTokenAuthenticator when you create a custom security token. If you wanted to override the default authentication or authorization behaviors for built-in security tokens, derive from one of the classes that derive from SecurityTokenAuthenticator, such as SamlSecurityTokenAuthenticator.

When you derive a class from SecurityTokenAuthenticator, override the following two methods: ValidateTokenCore and CanValidateTokenCore. The CanValidateTokenCore method determines whether this security token authenticator can authenticate a specific security token. The ValidateTokenCore method authenticates the security token and establishes a set of authorization policies for authorization. The authorization policies map the claims found in the security token to claims required by the application.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
