Removed features from Leopard

"NetInfo functionality has been removed from Mac OS X entirely." from here

This concerns me, as someone who has recently spent time dispelling the myth that macs crash a network. I attached a dozen macs to our corporate network with no ill effects, more so I made them authenticate against our active directory using NetInfo manager.

Where am I to find these settings in the future ? Surely Apple isn't abandoning their integration features, it was always a good stick to beat the ignorant with.
