SuperAdminSid String No S-1-5-22

The ID of a super admin. The ID must meet the following requirements:

  • The ID starts with S and does not contain letters except S.
  • The ID contains at least three hyphens (-) as delimiters.

Example: S-1-5-22 and S-1-5-22-23.

HomeDirPath String No /home

The home directory of each user. Each user-specific home directory must meet the following requirements:

  • Each segment starts with a forward slash (/) or a backslash (\).
  • Each segment does not contain the following special characters: <>":|?*.
  • Each segment is 0 to 255 characters in length.
  • The total length is 0 to 32,767 characters.

For example, if you create a user name A and the home directory is /home, the file system automatically creates a directory named /home/A when User A logs on to the file system. If the /home/A directory already exists, the file system does not create the directory.

Note User A must have the permissions to create folders in the /home directory. Otherwise, the file system cannot create the /home/A directory when User A logs on to the file system.
