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).
