I'm implementing RTC-Git integration with node.js following the information of this wiki
https://jazz.net/wiki/bin/view/Main/RTCGitIntegrationSetupUsingNode

The server operating system is RedHat 7.2 and RTC version is  6.0.3 (configured with express setup)

I've configured the node server choosing BASIC authentication and it start without problems.
Unfortunately, when I try to connect to server url (http://rh72:9999/git/MyPrj) I receive an HTTP 500 Internal server error.

Setting the environment variable RTC_GIT_SERVER_TRACE_LEVEL to 4, I obtain the following messages
[root@rh72 server]# node main.js

Server started. Listening at port 9999.

When I insert the credentials I receive the following error message
24 Apr 10:16:06 - Services ERROR basicAuth(): RTC might not be started in Basic mode.

What is the Basic mode? My authentication setting is Liberty Basic Registry. Is it correct?

Thanks in advance.
Bye.
