No-auth Windows broker fails client connection with "Selected mechanism not
supported"
--------------------------------------------------------------------------------------
Key: QPID-1896
URL: https://issues.apache.org/jira/browse/QPID-1896
Project: Qpid
Issue Type: Bug
Components: C++ Broker
Environment: Windows XP SP 3, VC++ 9.0
Reporter: Pete MacKinnon
If a client offers any non-empty auth mechanism (e.g., "PLAIN"), the windows
C++ broker will fail to start/tune the connection with "Selected mechanism not
supported" eventhough it has authorization disabled ("--auth=no").
void ConnectionHandler::start(const FieldTable& /*serverProps*/, const Array&
mechanisms, const Array& /*locales*/)
{
checkState(NOT_STARTED, INVALID_STATE_START);
setState(NEGOTIATING);
sasl = SaslFactory::getInstance().create(*this);
std::string mechlist;
bool chosenMechanismSupported = mechanism.empty();
for (Array::const_iterator i = mechanisms.begin(); i != mechanisms.end();
++i) {
if (!mechanism.empty() && mechanism == (*i)->get<std::string>()) {
chosenMechanismSupported = true;
mechlist = (*i)->get<std::string>() + SPACE + mechlist;
} else {
if (i != mechanisms.begin()) mechlist += SPACE;
mechlist += (*i)->get<std::string>();
}
}
if (!chosenMechanismSupported) {
fail("Selected mechanism not supported: " + mechanism);
}
