Covers creating users and groups, creating datasets with SMB presets, configuring ACLs (both default built-in users and custom group-based permissions), applying permissions recursively, and a key gotcha: SMB service must be restarted for group membership changes to take effect. Also touches on advanced share settings like bind IP addresses, access-based enumeration, host allow/deny, and special share types (Time Machine, Final Cut Pro). ## Full article daily.dev links to this article rather than hosting it.
