Table 3-2 NT Access Type Maps to UNIX Permission (continued)

r--Special Access
When mapping to UNIX file permissions from NT, you will not be able to add new NT ACL
entries because only the owner, owning group and other ACL entries are supported by UNIX
permissions. UNIX ignores unrecognized entries. Conversely, you cannot delete any of the three
entries listed above as these entries are required by UNIX.
Pre-defined NT Permissions
The Windows NT Explorer ACL interface allows you to choose predefined permissions like
Change and Full Control in addition to creating custom Special Access permissions.
Figure 3-1 Windows NT Explorer ACL Interface
If you use pre-defined NT access types to set permissions on a Samba share, the permissions that
are displayed later will not match what you set in NT.
For example, Full Control will become rwx on the Samba server, and when it is displayed on the
Windows NT client, it will show up as Special Access (RWX).
