RTCClient: Failed POST request at authenticated/j_security_check with response: Error 404: Not Found

@dixudx !
I am implementing integration with RTC v6.0.5 for my Python Flask app.

Problem is that POST request generated by the package fails (complete log):

Any suggestion please? Can it be that in RTC 6.0.5 another endpoint than '/authenticated/j_security_check' to be used?
