ONTAPI to get windows name and SID for local Unix User and Groups.

Anshul — Wed, 04 Jun 2025 11:17:46 GMT

Volume with security style mixed is shared as CIFS share.

When we access the CIFS share on windows machine and view permissions it shows UnixPermUid\root, UnixPermGid\root and UnixPerm\other for local Unix users and groups.

The SID for these local Unix user and groups are:

S-1-5-21-2038298172-1297133386-11111-0 for UnixPermUid\root

S-1-5-21-2038298172-1297133386-22222-0 for UnixPermGid\root

S-1-5-21-2038298172-1297133386-33333 for UnixPerm\other

The ONTAPI to fetch local Unix user users and groups are:

name-mapping-unix-group-get-iter
name-mapping-unix-user-get-iter

But these ONTAPI are not giving windows name and SID for local Unix users and groups.

How to get the windows name and SID for local Unix users and groups programmatically?

What is the ONTAPI to get windows name and SID for local Unix user and groups?

The way that Windows displays those names and SIDs is, as far as I understand it, an attempt by Windows to approximate UNIX mode bits into something that resembles the style of NTFS permissions. That being said, I don't think you'll be able to get that specific data from the ONTAPI.
