As root, I ran the command dseditgroup -o edit -a design -t group -n /NetInfo/DefaultLocalNode admin but when I hit return there was no response in the terminal, instead giving me a new command line. I logged out of Root and logged in as network user jimmy who is a member of OD group design, and tried to unlock a system preference padlock. Entering that user’s credentials would not unlock the padlock. I opened Terminal and ran dseditgroup -o checkmember admin and dseditgroup -o checkmember -n . admin and both returned jimmy is NOT a member of admin.
Any help would be appreciated.
