Hi,
The user and group can only be changed from Desktop Client. The imexutil utility allows import and export of artifacts. It can only, however, export users and groups and import is disabled. The user and groups is disabled to avoid any inconsistencies which can cause severe issues. If you are ok to restart DE, then look at this KD.
First create a group similar to SCHEDGRP, e.g SCHED2. Add your users to the group. Next export the groups.
imexutil.sh -h localhost -p 7500 -u user -w userpass -c "exportgroup -outdir /tmp/group"
When you export, all groups are exported. Delete all the other groups and leave the SCHED2. Save this in a separate directory which will be used to turn on the permissions.
Now, delete all the permissions in the SCHED2 group and export it again. Save the second version in a directory which will be used to turn off the permissions.
To turn on, follow the steps in the KD. Put the SCHED2.xml file with all the permissions in <installdir>/Resources/DBInit/Group. Restart DE. You should see all the permissions. Follow similar steps to remove the permissions.
Thank you,
