ntfsusermap - NTFS Building a User Mapping File
is the device containing the Windows system
whose users are to be mapped to current Linux system.
is another device containing files which are to be
accessed both by the Windows mentioned above and current Linux system.
the ntfsusermap command must be started as root, and the designated devices must
not be mounted.
Typing ntfsusermap with no args will display a summary of command arguments.
creates the file defining the mapping of Windows accounts to
Linux logins for users who owns files which should be visible from both
Windows and Linux.
It relies on existing files which were created on Windows, trying to locate
significant files and asking which Linux user or group should own them. When a
Linux owner or group is requested, the reply may be :
- the uid or gid (numeric or symbolic) of Linux owner or group of the file.
In that situation, no more file with the same Windows
owner will be selected.
- or no answer, when not able to define the owner or group.
In that situation another file owned by the same Windows
user or group may be selected later so that a mapping can be defined.
The mappings for standard Windows users, such as "Administrator" or
"All Users" are defined implicitly. As a consequence a user mapping
should never be defined as Linux root.
When there are no more significant files, ntfsusermap create the mapping file
into the file UserMapping in the current directory. This file has to be moved
to the hidden directory .NTFS-3G in the root of all the NTFS file systems to
be shared between Windows and Linux. This requires the file system to be
mounted, but the created file will not be taken into account if not present at
mount time, which means the file system has to be unmounted and mounted again
for the new mapping file to be taken into account.
No option is defined for ntfsusermap.

Several people made heroic efforts, often over five or more years which resulted
the ntfs-3g driver. Most importantly they are Anton Altaparmakov, Richard
Russon, Szabolcs Szakacsits, Yura Pakhuchiy, Yuval Fledel, and the author of
the groundbreaking FUSE filesystem development framework, Miklos Szeredi.
