Process for Running a GroupWise Agent as Non-Root Create a Linux user to run the agents useradd -s /bin/false gwagent Create /etc/opt/novell/groupwise/agents/uid.conf Edit the file with only the name of the agent user Delete uid.run from domain, gwia & post office directories Bring down all GroupWise Agents (rcgrpwise stop) Start the Agents (rcgrpwise start) Agents create a uid.run file in domain/po/gwia directory 11 Ownership of the files also changes Novell, Inc.
