Hi,

After successfully login to cas and redirect back, getting below error again and again while accessing api.

[2] [TypeError: Cannot read property 'authenticationfailure' of undefined] [2] [Error: CAS authentication failed.] My service is pointing to localhost. Is there a way to debug ?

I've made a console log of the result object and I've got : 

{"html":{"head":{"title":"404 Not Found"},"body":{"h1":"Not Found","p":"The requested URL //serviceValidate was not found on this server."}}}

so, obviously no result.serviceresponse.authenticationfailure...

I suspect an parse error form index.js Line 67. but can't resolve it.

I'm doing a rewrite of this module (with no API-breaking changes) and I'm going to validate the structure of the CAS server's response. All this will do it provide a more useful error message, though.

If the CAS server in the test cases was operating correctly and on the correct version, then this might be a problem with slashes. I'll be properly building and checking my request URLs in the new version.
