Hi, I am trying to use iwmodelc to invoke a already created workflow model. This command is inside a script. Whenever i execute the script from commandline or iwmodelc itself from commandline it works fine. But if I call this script in a workflow external task then I always get the following error."unable to get curret user name". I have checked iwmodelc script and this error is present there if the script is not able to get the user name from any where.I have no clue why while invoking within the workflow this is happening. Please suggest.Env: Solaris 10, TS6.7.1 SP1, Workflow Model 1.0.0.1
