The SecurityTokenAuthenticator type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | SecurityTokenAuthenticator | Initializes a new instance of the SecurityTokenAuthenticator class. |
| Name | Description | |
|---|---|---|
![]() | CanValidateToken | Gets a value indicating whether the specified security token can be validated by this security token authenticator. |
![]() | CanValidateTokenCore | When overridden in a derived class, gets a value indicating whether the specified security token can be validated by this security token authenticator. |
![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
![]() | ValidateToken | Authenticates the specified security token and returns the set of authorization policies for the security token. |
![]() | ValidateTokenCore | When overridden in a derived class, authenticates the specified security token and returns the set of authorization policies for the security token. |
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.
