Apple has released v6.0 of AirPort Utility for Lion, and the response from the IT support community has been very negative. Airport Utility v6.0 is repackaged version of it’s iOS counterpart, tailored to home users, and is missing the ability to configure most advanced features including LDAP, wide-channels, Mac address access control, transmit power, time server settings, network extending, DHCP Client ID, SNMP, and IPV6 settings.

Luckily Apple still has v5.6 of AirPort Utility still available for download (which also requires Lion). If you are running Lion, and depend on configuring any of these advanced features, do not update to v6.0!
