Root access is required for uninstalling.
Open a shell and execute the following command:
/var/opt/novell/iManager/nps/UninstallerData/UninstalliManager
As noted during the uninstall routine, the iManager uninstall process does not uninstall NICI. You can uninstall NICI separately, if desired.
IMPORTANT:If eDirectory is installed on the same server as iManager, NICI is required to continue to run eDirectory.
