Quota user and group IDs
Quotas are generally specific to users or groups of users, and the IDs can be specified in a variety of ways.
Users and groups can be specified in either NFS format or SMB/CIFS format, depending on certain conditions.
For an NFS user or group, it can be NFS v2/3 format with its UNIX user/group ID optionally registered in the HNAS user/group mappings. For example, if user "NFSuser" with its UNIX user ID 501 is added as a user mapping, then you can add a user quota with the user named “NFSuser”, and the same would be true for a group quota specified by name, provided that name was a valid group mapping. For NFS v4 format, the user or group must attach its host name in the format of user@host or group@host, e.g.NFSv4Group@deb5010-57-75.
SMB/CIFS users or groups can be discovered from the Windows Domain Controller or input by an HNAS user. Usually they are in the format of "Domain\user" or "Domain\group", such as "BUILTIN\Current User" or "BUILTIN\Current Group". Backslash characters must be escaped when provided as input parameters.
