I can reproduce the issue you reported on centOS:
lsadm : lsadm nobody user1
lsadm : lsadm nobody
and it can be fixed by change line 905 of functions.sh from
usermod -G $WS_GROUP lsadm
usermod -a -G $WS_GROUP lsadm
we'll estimate if this change has any other side effect.
however, is it a good practice?
assume you have 1000 users, will you add lsadm to all these 1000 groups?
