I am attempting to use renderProblem.pl and WebworkClient.pm on Ubuntu 12.04. I am able to produce output in the browser, but it is only rendering the WebworkService error:

Error in xmlrpcCall to server: Server, Unknown exception when trying to verify authentication. at /opt/webwork/webwork2/lib/WebworkWebservice.pm line 223.

Do I need to change the original values of $XML_PASSWORD and$XML_COURSE, or is this something else going on?
