Managing UNIX Permissions Using NT Security Dialogs
Windows NT clients can use their native security settings dialog box to view and modify the
underlying UNIX permissions.
This ability is careful not to compromise the security of the UNIX host on which Samba is running and
still obeys all the file permission rules that a Samba administrator can set.
Samba does not attempt to go beyond POSIX ACLs, so the various finer-grained access control
options provided in Windows are actually ignored.
