Methods

Name Description
Public method CheckReadPermission Evaluates whether the given user should be able to read the permissions for the given token. Note that implementing this function will cause the ReadPermission defined in the namespace not to be checked. If you want to implement this interface and still have those checked then make sure to derive from the DefaultSecurityNamespaceExtension and not override this method. This method should throw some type of access exception if the user does not have read permission on this token.
Public method CheckWritePermission Evaluates whether the given user should be able to change permissions. Note that implementing this function will cause the WritePermission defined in the namespace not to be checked. If you want to implement this interface and still have those checked then make sure to derive from the DefaultSecurityNamespaceExtension and not override this method. It is expected that this function will throw if the caller should not be able to write permissions
Public method HandleIncomingToken Allows the implementor to validate or change the incoming token. These functions will only be called when tokens are coming in from the Web service.
Public method HandleOutgoingToken Allows the implementor to validate or change the outgoing token. These functions will only be called when tokens will be going over the Web service.
Public method HasPermission This will be called every time that a permission decision is being made and allows the implementor to override the preliminary decision. Note, if a PermissionEvaluationCallback is provided to the function, it will override this decision.
Public method HasReadPermission Evaluates whether the given user should be able to read the permissions for the given token. Note that implementing this function will cause the ReadPermission defined in the namespace not to be checked. If you want to implement this interface and still have those checked, then make sure to derive from the DefaultSecurityNamespaceExtension and not override this method.
Public method HasWritePermission Evaluates whether the given user should be able to change permissions. Note that implementing this function will cause the WritePermission defined in the namespace not to be checked. If you want to implement this interface and still have those checked then make sure to derive from the DefaultSecurityNamespaceExtension and not override this method. It is expected that this function will not throw if the caller should not be able to write permissions.
Public method QueryEffectivePermissions Called every time that the security namespace is about to return effective permissions to either the server API or the Web service. This allows the implementor to modify the final result.
Public method QueryPermissions Called every time that the security namespace is about to return AccessControlLists to either the server API or to the Web service. This allows the implementor to modify any of the ACLs that are being returned.
Public method ThrowAccessDeniedException
