The Grouper Daemon is a process that can handle many tasks.  In Grouper v2.4+, all daemon jobs are visible in the Grouper UI. 

Starting in v2.5+: run the Grouper container with the "deamon" argument or the appropriate env vars set (see v2.5 container documentation)

Starting (command line, not needed in v2.5):

gsh.sh -loader

Starting in Unix (command line, not needed in v2.5):

nohup gsh,sh -loader &

Stopping: find the process and kill it

See this document to have a unix service which controls the loader

Note: it is also possible to run the loader in another webapp if you like

The long-term roadmap is to have the ability to run the loader in a web services instance or UI instance
