Setting Up Permissions

TrueNAS provides basic permissions settings and an access control list (ACL) editor to define dataset permissions. ACL permissions control the actions users can perform on dataset contents and shares.

An Access Control List (ACL) is a set of account permissions associated with a dataset that applies to directories or files within that dataset. TrueNAS uses ACLs to manage user interactions with shared datasets and creates them when users add a dataset to a pool.

TrueNAS offers two ACL types: POSIX and NFSv4. For a more in-depth explanation of ACLs and configurations in TrueNAS, see our ACL Primer.
