Windows clients cannot change any le or directory permissions. Read, write, and execute access is controlled by the UNIX
permissions for Windows les and directories, which you set in Group Manager.
• NTFS — Controls le 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 le 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 benecial to set UNIX security style for UNIX clients and set NTFS security style for
Windows clients.
