Apple released Mac OS X 10.7.3, an update that fixes a number of bugs that been plaguing MacWindows readers since Lion's release, including several Active Directory and file sharing problems. In fact, yesterday's update appears to be focused on these areas.
Apple says the update fixes Active Directory problems for .local domains, including slow Active Directory binding and other binding problems. Last November, Apple recommended using IPv6 records in a DNS server as a workaround. Other readers reported that turning off DNS multicast was an effective workaround.
The Lion 10.7.3 update also fixes a problem with the home directory didn't appear as a Dock item for Active Directory users with mobile accounts, a problem that has been reported in our forums. Another fix is with Active Directory schemas that have been extended with the "apple-user-homeDirectory" and "apple-user-homeurl" attributes. This is another problem that a reader has previously reported.
Apple said that the update improves binding to read-only Active Directory domain controllers, and allows login with an Active Directory username that contains a space. Mac OS X 10.7.3 also improves reliability of Dynamic DNS (DDNS) updates by Active Directory clients, according to Apple, and allows NIS users with MD5-hashed passwords to log in.
There are a number of file sharing bugs fixed, though Apple didn't list them all. It said that the update fixes "compatibility issues with Microsoft Windows file sharing." (MacWindows Lion File Sharing Tips and Reports documents numerous SMB file sharing problems.) Authenticating to an SMB DFS share, a problem we have previously reported, is also fixed. Apple did not mention if the update fixes Lion's inability to scan to SMB network scanners. Apple also addressed problems logging in to Mac OS X Lion with smart cards.
There are also a couple of Wi Fi connection improvements, including fixing a problem resuming a Wi Fi connection when waking from sleep and a problem with opening Safari before joining a wireless network. Problems logging in with smart cards have also been address, according to Apple.
The update includes several dozen security improvements.
