Thus, we must now use the ds* (directory services) applications in Terminal. As of right now, I don't know of any GUI application equivalent of NetInfo manager, only the applications like dscl, dscacheutil, dsenableroot, and so forth. As an example, here's how to print out all the user accounts:
dscacheutil -q group
Hopefully there will be some GUI interface to these tools developed as time goes on.
