First I would confirm how they are logged into their Mac.
I know of no reason for this if they are logged in correctly, standby and hopefully someone else will chime in.

Most preferences are unavailable while running in multi-user mode. Tell your client they must log out of MU mode - disconnecting other users - and then they'll be able to access Preferences.
