NFSv4 ACL Management Overview

NFSv4 uses ACLs (Access Control Lists) for fine-grained permission control. The two main commands for managing NFSv4 ACLs are:

1. nfs4_getfacl

Purpose:

To view the NFSv4 ACLs of a file or directory.

Syntax:

nfs4_getfacl <file_or_directory>

Example output:

A:fd:[email protected]:rwaDxtTnNcCy

Explanation:

• A: → ACL Entry (Access)
• fd → Flags (f = file-inherit, d = directory-inherit)
• [email protected] → User principal
• rwaDxtTnNcCy → Permissions

2. nfs4_setfacl

Purpose:

To add, set, modify, or remove ACL entries on files or directories.
