User Apps are not selectable in Windows SMB security setting

The Apps user are not available for selection in Windows SMB security settings.

If I want to add apps user a specific folder or file a set of permission, I am unable to do that in Windows via SMB.

Use case example1:

  • pool

    • dataset

      • folder1

      • folder2

Apps user have modify permission at the dataset but no inherit. Then modify on folder1, read only on folder2.

container bind mount to /pool/dataset:/folder

Example 2:

  • pool

    • dataset

      • folder1

      • folder2

I want apps user to have rw permission on folder1 but read-only on folder2.

container bind mount to /pool/dataset/folder1:/folder1 and /pool/dataset/folder2:/folder2
