== Samba Active Directory für DynDNS Updates mit GSS-TSIG ==
Ziel: Einfacher DynDNS Update Dient (mit Kerberos / [http://en.wikipedia.org/wiki/Generic_Security_Service_Algorithm_for_Secret_Key_Transaction GSS-TSIG]

== lxc Container ==
* Debian 7
* Samba 4.1.13 / Kerberos 5
* IPv4: 217.115.11.136
* IPv6: 2001:4dd0:fb82:c3d2:a800:5bff:fe06:c2b7

== DNS ==
* global.hq.c3d2.de

== DNS Nameserver / SRV Records ==
* space.c3d2.de.   IN NS   global.hq.c3d2.de.
* _dns-update._tcp.c3d2.de.   IN SRV   5 0 53 space.c3d2.de.
* _dns-update._udp.c3d2.de.   IN SRV   5 0 53 space.c3d2.de.

== Server Installation ==

<pre>
apt-get install samba

service samba stop

rm /etc/samba/smb.conf
rm -rfv /var/lib/samba
mkdir /var/lib/samba
mkdir /var/lib/samba/private
</pre>

== neue Samba Provisionierung ==

<pre>
/usr/bin/samba-tool domain provision --use-ntvfs --use-rfc2307 --function-level=2008_R2 --realm=SPACE.C3D2.DE --domain=SPACE --adminpass='GEHEIM' --server-role='dc' --dns-backend=SAMBA_INTERNAL
</pre>

Samba läuft mit virtuellen sysvol NTACLs, zukünftig fehlende +s3fs Daemon Unterstützung da --use-xattrs=yes nicht in dem lxc Container mit btrfs unterstützt wird!

<pre>
[root@global:~]# /usr/bin/samba-tool domain provision --use-ntvfs --use-rfc2307 --function-level=2008_R2 --realm=SPACE.C3D2.DE --domain=SPACE --adminpass='GEHEIM' --server-role='dc' --dns-backend=SAMBA_INTERNAL
You are not root or your system do not support xattr, using tdb backend for attributes. 
not using extended attributes to store ACLs and other metadata. If you intend to use this provision in production, rerun the script as root on a system supporting xattrs.
