SUMMARY

This article discusses how file, directory, and printing permissions compare between Windows NT Advanced Server and LAN Manager version 2.x.

MORE INFORMATION

File and Directory Permissions

On a LAN Manager for OS/2 system, you can control access to all files and directories under the FAT, HPFS, or HPFS386 file systems. On a Windows NT system, you can control users' access to directories and files on drives formatted to use the Windows NT file system (NTFS). Drives formatted to use FAT and HPFS do not support Windows NT security. You can, however, secure Windows NT shared directories no matter what file system is in use.

The standard permissions for files and directories and their meanings are shown in the following tables, along with the individual permissions each standard permission represents.

LAN
Manager     NTFS                 Description
-----------------------------------------------------------------------

R           Read (RX)            User can read the contents of the
                                 file and run it if it is an
                                 application.

W
(Write)     Change (RWXD)        Lets the user open and write to a
                                 file, changing its contents. Windows
                                 NT allows deletion of the file.

D           N/A                  Lets the user delete files.
(Delete)

X
(Execute)   N/A                  Lets the user run a program, but
                                 not read or copy it.

A           N/A
(Change Attributes)              Lets the user change file attributes.

P           N/A
(Change Permissions)             Lets the user grant permissions for
                                 the file to other users.

Y           Full Control (All)   For LAN Manager, serves as a shortcut
(Yes)                            to RWCDA permissions. When you give a
                                 user Y permission, you are granting
                                 RWCDA permissions.

                                 For Windows NT, enables user to read,
                                 modify, delete, set permissions for,
                                 and take ownership of the file.

N           No Access            Prevents a user from using the file
(No)                             or directory in any way, even if the
                                 user is a member of a group that has
                                 been granted access to the file. On
                                 LAN Manager, Y access given to a user
                                 overrides N access given to a group.
                                 On Windows NT, deny access takes
                                 precedence. For example, if a user
                                 has Full Control access for a file,
                                 but is a member of a group that has
                                 No Access for the same file, access
                                 is denied.
                

In the second column of the following table (for NTFS directory permissions), the first set of individual permissions applies to the directory itself, and the second set of individual permissions applies to new files subsequently created in the directory.

Directory Permissions

LAN
Manager     NTFS                   Description
-----------------------------------------------------------------------

R           Read (RX)(RX)          User can read files in the
(Read)                             directory and run applications in
                                   the directory.

W           Change (RWXD)(RWXD)    User can read and add files and
(Write)                            change the contents of current
                                   files.

C           Add                    A user with C permission can create
(Create)    (WX) (Not Specified)   a file and after creating it, can
                                   read from or write to the file
                                   until closing it.

            Add & Read             Add enables a Windows NT user to
            (RWX) (RX)             add files to the directory but not
                                   to read the contents of current
                                   files or change them.

                                   Add & Read enables a user to add
                                   files to the directory and read
                                   current files, but not to change
                                   any files.

D           N/A                    Users can delete files and
(Delete)                           subdirectories within the shared
                                   directory but cannot delete the
                                   shared directory itself.

X           N/A                    Lets the user run a program in the
(Execute)                          directory, but not read it or copy
                                   it.

A           N/A
(Change Attributes)                Lets the user change the attributes
                                   of files in the directory.

P           N/A
(Change Permissions)               The user can change the permissions
                                   for the directory or files in the
                                   directory.

Y          Full Control
(Yes)      (All)(All)              For LAN Manager, serves as
                                   shortcut to RWCDA permissions. When
                                   you give a user Y permission, you
                                   are granting RWCDA permissions.
                                   User can read and change files, add
                                   new ones, change permissions for
                                   the directory and its files, and
                                   take ownership of the directory and
                                   its files.

N          No Access
(No)       (None)(None)            Prevents a user from using the file
                                   or directory in any way. Usually,
                                   you can prevent a user from
                                   accessing a file or directory
                                   simply by not giving the user any
                                   permissions to it; however, you
                                   must use N permission to prevent a
                                   specific user from accessing a file
                                   while granting access to the file
                                   or directory to a group the user
                                   belongs to. For Windows NT, users
                                   cannot access the directory in any
                                   way, even if they have Full Control
                                   access through membership in a
                                   group.

N/A        List (RX)               User can only list the files and
(Not Specified)                    subdirectories in this directory and
                                   change to a subdirectory of this
                                   directory. User cannot access new
                                   files created in this directory.
                

NOTE: Permissions on shared Windows NT directories that are not NTFS are identical. Note that if a directory is both shared and on an NTFS volume, permissions are cumulative over the network.
