How to create and where to put Custom Jars

#1

I am trying to restrict data source creation in CE version to 1 user only. so that user will be admin rest of them will be regular users (user role). I have created the CustomSecPackDACDaemonModule extending DACDaemonModule. However it didnt work. Did anyone try this and were successful?

We are using CE for all POC work in our nonprod area.
