* Version `4.18` introduced a `security.NTACL` feature intended to allow samba-dc to run within a container without the `CAP_SYS_ADMIN` permission. See the section _New option to change the NT ACL default location_ in the [features added/changed](https://wiki.samba.org/index.php/Samba_Features_added/changed) documentation. The helm chart defined here can be locally modified to support this but it's left as an exercise for advanced users.
