Comment 1 James B. Byrne 2016-07-13 13:41:04 UTC
I discovered that the --use-ntfs option is not supported in samba-4.4. When the original 4.3 install was done it was performed on a zfs backing store which required the use of that switch.  I suspect that a samba-4.4 upgrade cannot be made to such a configuration.

I have searched for any discussion of this and have found nothing other than a single report to the FreeBSD Ports maintainer for Samba regarding the missing option.  My present understanding is the zfs file systems are not supported by samba-4.4 when used as an AD-DC and as such the ufs store must be employed instead.  If I am wrong I would appreciate guidance on how to proceed to reslove this.

I was unable t find any Samba4 changelog mentioning the removal of --use-ntfs.  Could ypou point me to it please?
Comment 2 James B. Byrne 2016-07-27 20:48:08 UTC
This appears to be an issue which is known to the samba ports maintainer for FreeBSD and for which there is as yet not remedy.  We are therefore running on Samba43.

see vfs_zfsacl. Closing this one as this is not a bug. Please consult the mailing list on how to use zfs with Samba.
