How does the Solaris/Linux command chmod work on home directories?
The chmod command in Solaris/Linux will add or modify three Access Control Entries (ACEs) on the file(s)/diretory(ies) being processed. One for the owner, one for the default group of the owner, and one for the builtin group Everyone in the Active Directory domain. For a good description of how read, write, execute, and extended attributes are mapped to Solaris ZFS, please refer to Sun’s website for documentation or contact TSG.
