Configure NGINX with specific user without user needing *ALLOBJ Authority

User was seeing the following error in their NGINX log file when trying to start or restart the NGINX server via:

Errors showed up in the log file in file: /QOpenSys/var/log/nginx/error.log

Accessing error.log from 5250 command line:

This seems to be related to setting up an appropriate user profile to run the NGINX server and threads under.

By default the main thread user will be the user who started the NGINX server. And worker thread jobs run under user profile: QTMHHTTP by default.

What we want is for the main thread and worker threads to run under the same user profile. See the following GitHub article for a resolution: https://github.com/richardschoen/howtostuff/blob/master/nginx-ibmi-without-allobject-auth.md
