Exceptions

InvalidRequestException

request is null.

-or-

The RequestType property of the request is not set to Issue.

-or-

The KeyType property of the request is not null or one of the constants defined in the KeyTypes class.

-or-

The KeyType of the request is Bearer and the KeySize element is present, but its value is not equal to zero.

UnsupportedTokenTypeBadRequestException

The STS does not support the request token type (based on the value of the TokenType property of the request).

Remarks

The ValidateRequest method is called from the token issuance pipeline (the Issue method) to validate the incoming RST. The RST is validated against the requirements (policy) of the STS and an appropriate exception is thrown if it is not valid.

The default implementation of the SecurityTokenService class supports only the RST-RSTR pattern and only the Issue binding of the WS-Trust specification (the RequestType property of the request must be set to RequestTypes.Issue). The default implementation of this method enforces these requirements (and others noted in the exceptions section). You can override this method if you must enforce different validation requirements for your custom STS.
