Windows Server 2012 R2 NFS identity mapping linux client

I'm trying to identity map a Ubuntu 12.04 machine to a NFS share on a Windows 2012 R2 machine.

I have a limited amount of Ubuntu machines, all with the same user.

This:

States that I can identity map if I create a passwd and group file under:

System32/drivers/etc

I did so with passwd as follows:

localhost\user:x:1000:1000

group:

localhost\UNIXuser:x:1:user

On the Windows machine I created the UNIXuser group with the user being a member.

The windows event viewer (ServicesForNFS-Server\IdentitiyMapping) says:

A syntax error was found on line 1 when loading C:\Windows\System32\drivers\etc\passwd. The file will not be used as a mapping source.

C:\Windows\System32\drivers\etc\group will be used as a mapping source.
Solution

  • 1) On Windows NFS client, create local user <Unix_user>

    2) Edit C:\Windows\System32\Drivers\etc\passwd
    <localhost>\<Unix_user>:x:<Unix_UID>:<Unix_GID>:User Description,,,:c:\users\<Unix_user>

    3) Edit C:\Windows\System32\Drivers\etc\group
    <localhost>\<Unix_group>:x:<Unix_GID>:<Unix_UID>
