Apple has released Mac OS X 10.7.5 Lion Server with fixes for a variety of commonly used services. The update provides fixes for maintaining the Spotlight index when changing share point settings, creating and connecting to the Open Directory master, using Software Update, and using Profile Manager to set how frequently the Mobility sync interacts with mobile accounts. It also improves the reliability of password authentication and changing an Xsan metadata controller into a client. The updates come in two editions — a delta update for those upgrading from 10.7.4 Lion Server (1.22 GB) and a Combo update for those upgrading from previous versions of Lion Server (1.99 GB).

Improve Apple Services with AirPort Base Stations
You can make iChat file transfers, iDisk, and Back to My Mac work better by turning on a setting with Apple AirPort base stations released starting in 2003. Launch AirPort Utility, select your base station, click Manual Setup, choose the Internet view, and click the NAT tab. Check the Enable NAT Port Mapping Protocol (NAT-PMP) box, and click Update. NAT-PMP lets your Mac OS X computer give Apple information to connect back into a network that's otherwise unreachable from the rest of the Internet. This speeds updates and makes connections work better for services run by Apple.
