Failed to initialize Authentication Session, (name can't be null)

Hi there

I’m new to WM so apologies in advance if some of the questions (and the way they might be asked) sound stupid.

I’m getting a “Failed to initialize Authentication Session, (name can’t be null)” error when trying to start up the Workflow Services by running the command: ./allservers.ksh start

I have another Instance of Workflow which starts up fine & connecting to the same Oracle Database. I don’t seem to be getting this problem when I try to logon without using Site Central.

Running on Red Hat Linux connecting to an Oracle 10G DB.
