[Samba] Samba4 AD DC using s3fs an OpenIndiana/Illumos/Solaris

[Henner Gratz]

Hello!

I've just built my first samba4 (4.0.5) on an OpenIndiana machine 
without any problems.
But when it comes to the provision step the problems begin. Everything 
is fine, if I
call samba-tool with the --use-ntvfs option. But I want to use samba4 
with s3fs because
of the support for newer SMB protocol versions.

But when I call samba-tool without --use-ntvfs option I got the following:


root at openindiana:~# /usr/local/samba/bin/samba-tool domain provision
Realm: domain.local
  Domain [domain]:
  Server Role (dc, member, standalone) [dc]:

chosen realm '%s'!  Please remove the smb.conf file and let provision 
generate it" % (lp.get("realm").upper(), realm, lp.configfile))


I know that samba uses POSIX ACLs while OpenIndiana/ZFS uses NFSv4 ACLs, 
but I hoped
that there is a way to configure samba4 to work with s3fs on Solaris 
machines as well.
Unfortunately I wasn't able to find anything about this topic with 
google and friends.
Does somebody on this list know more about it?

Thank you very much for any advice in advance!
