ACLs and samba4

[Janos Dohanics]

Hello List,

I'm getting an error as I try to use /usr/local/bin/samba-tool domain
provision (FreeBSD 10.0-STABLE #0 r269827 i386):

#/usr/local/bin/samba-tool domain provision
[...]
Setting up self join
ERROR(<class 'samba.provision.ProvisioningError'>): Provision failed - ProvisioningError: Your filesystem or build does not support posix ACLs, which s3fs requires.  Try the mounting the filesystem with the 'acl' option.

But I did enable ACLs using tunefs(8):

# tunefs -p /dev/mirror/gm6
tunefs: POSIX.1e ACLs: (-a)                                enabled

# cat /etc/fstab

/dev/mirror/gm2	/		ufs	rw	1	1
/dev/mirror/gm3	none		swap	sw	0	0
/dev/mirror/gm4	/var		ufs	rw	2	2
/dev/mirror/gm5	/tmp		ufs	rw	2	2
/dev/mirror/gm6	/usr		ufs	rw,acls	2	2

What am I doing wrong?
