NTFSUSERMAP(8)              System Manager's Manual             NTFSUSERMAP(8)

NAME
       ntfsusermap - NTFS Building a User Mapping File

SYNOPSIS
       ntfsusermap windows-system-device [other-ntfs-device...]

       Where windows-system-device is the device containing the Windows system
       whose users are to be mapped to current Linux system.

       And other-ntfs-device is another device containing files which  are  to
       be  accessed both by the Windows mentioned above and current Linux sys-
       tem.

       the ntfsusermap command must be started as root, and the designated de-
       vices must not be mounted.

       Typing ntfsusermap with no args will display a summary of command argu-
       ments.

DESCRIPTION
       ntfsusermap 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 map-
       ping 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.

OPTIONS
       No option is defined for ntfsusermap.

EXAMPLES
       Map the users defined on the Windows system present on /dev/sda1 :

              ntfsusermap /dev/sda1
