Apple released Apple Server Admin Tools 10.5.5 on Tuesday. The update for Mac OS X Server Utility now correctly enables and shows the status of RADIUS or Kerberos authentication for PPTP VPN services.
The update also added the ability to reliably display the primary IP address for 802.11n-enabled AirPort Extreme Base Stations, and sort by value in the DNS service Zones tab. Apple System Configuration Settings bugs have been fixed, the Add Packages and Post-Install Scripts actions now work correctly when creating NetInstall images, and browsing when adding or removing computers from groups has been improved.
Apple Server Admin Tools 10.5.5 is available via the Software Update application, or as a downloadable installer at the Apple Support Web site.
