OpenSAML user discussion

["Manuel Ernstberger" <>]

Hello,

if I add an Authenticating Authority to the AuthnContext of an assertion and 
try to marshal that assertion then I get a class cast exception. The complete 
error message is:

AxisFault
 faultCode: {http://schemas.xmlsoap.org/soap/envelope/}Server.userException
 faultSubcode: 
 faultString: java.lang.ClassCastException:

With this code I add the authenticating authority:

AuthenticatingAuthorityBuilder authnAuthBuilder = 
(AuthenticatingAuthorityBuilder)builderFactory.getBuilder(AuthenticatingAuthority.DEFAULT_ELEMENT_NAME);

AuthenticatingAuthority authnAuth = 
authnAuthBuilder.buildObject(namespaceURI,localName,namespacePrefix); 
                  authnContext.getAuthenticatingAuthorities().add(authnAuth);


Could you please look whether there's a bug in opensaml 2.0 tp2? Or am I 
doing something wrong? Is it perhaps necessary to cast the authenticating 
authority object?


Regards,
Manuel
