[Samba] Samba4 Classicupgrade Failed

[Mario Codeniera]

Uprading on a New Server (Running on Centos 6.3, OpenLDAP 2.4.23 migrated
the data from existing server). I dunno know where to fix it, or someone
gave some idea how it works?

[root at gaara samba]# /usr/local/samba/bin/samba-tool domain classicupgrade
--dbdir=/home/ambot/Downloads/var/lib/samba --use-xattrs=yes
--realm=ewanko.local /etc/samba/smb.conf
