Windows clients cannot change any file or directory permissions. Read, write, and execute access is controlled by the UNIX permissions for Windows files and directories, which you set in Group Manager. • NTFS - Controls file access by Windows permissions in all protocols. A client can change the permission and ownership by using the Windows Security tab. This security style is the default style. All access permissions are controlled by the Windows administrator through the use of access control lists or share-level permissions. • Mixed - Supports both NTFS and UNIX security styles. The permissions and ownership for a file or directory will be the last ones set. Permissions and access rights are automatically translated from one protocol to another. A Windows user can override UNIX user settings, and a UNIX user can override Windows user settings. In multiple protocol environments, it can be beneficial to set UNIX security style for UNIX clients and set NTFS security style for Windows clients.
