only primary group. We specify all secondary groups one byone.

we do not take care of users, only groups.
here is an example of FS in our farm:
GROUPCFG[picvo] FSTARGET=12 QDEF=lhpicvo
GROUPCFG[picvosgm] FSTARGET=44 QDEF=lhpicvo MAXPROC=3
GROUPCFG[picvoprd] FSTARGET=44 QDEF=lhpicvo
QOSCFG[lhpicvo] FSTARGET=1 MAXPROC=50
** MAXPROC in picvosgm is ignored but doc says it mut work.
