recoiledsnake writes "The upcoming release of Mac OS X 10.7 Lion Server will remove the formerly bundled open source Samba software and replace it with Apple's own tools for Windows file sharing and network directory services. In both Mac OS X Server and client editions, Samba enables Macs to share files with Windows clients on the network and access Windows file servers. It has also later allowed Mac OS X Server to work as an NT Domain Controller to manage network accounts and make roaming profiles and home directories available to Windows PC users. However, the Samba team has moved active development of the project to the more strict GPLv3 license, which prevents Apple from using the software commercially. Apple is now said to be recommending Active Directory to users who are still dependent upon the older NT Domain Controller network directory services. Apple has previously stopped contributing code to GCC and started looking at other options like LLVM because of GCC's switch to GPLv3."
