ROOT user set up on the BF Console, cannot execute a simple script on the BF Console

Hello,

I constantly have "API: access denied" failure when I do BuildForge build on the BF Console

the ticket was opened at https://jazz.net/jazz/resource/itemName/com.ibm.team.workitem.WorkItem/302262 regarding this matter.

Also there is information about it at https://jazz.net/forum/questions/119165/using-buildforge-7x-to-rtc-3x-build-definition-get-api-access-denied

Unfortunately, we currently can have only one BuildForge user, which is a ROOT User (it is our current limitation and we have to live with it - we cannot create the second user becuse of the licenses' limitations). And with this ROOT user I and my peer constantly get the error "API: Access denied" when we try to execute a simple script "echo hello" on the BuildForge.

What is really going on:

Each time after User's password change, the build (simple script execution) on the BuildForge, started from the Eclipse with the RTC plug-in, always runs successfully. All consecutive runs of the same script from the Eclipse IDE fail with the  "API: Access denied" error message.

Any input is appreciated.
