Description pt 2014-06-03 09:14:29 UTC

I have a working Samba3 installation with ldap backend on Debian Wheezy x64. I would like to upgrade to Samba4, so I test it on a virtual machine. I copied the PDC to the virtual machine, and set up debian backports, then installed Samba 4.1. I follow Samba Classic Upgrade SambaWiki.
samba-tools didn't find an ldb lib, so I created a link:
ln -s /usr/lib/x86_64-linux-gnu/ldb/ /usr/lib/x86_64-linux-gnu/samba/

samba-tool domain classicupgrade --dbdir=/var/lib/samba.pdc/private/ --use-xattrs=yes --realm=xy.site --dns-backend=Bind9.DLZ --option="interface=lo eth0" --option="bind interface only=yes" /etc/samba.pdc/smb.pdc.conf

I ran into the same problem with 4.1.13.

FYI, the troublesome LDAP entry was:

dn: uid=root,ou=People,dc=ucc,dc=gu,dc=uwa,dc=edu,dc=au
objectClass: sambaSamAccount
objectClass: account
displayName: root
sambaAcctFlags: [DU         ]
sambaSID: S-1-5-21-3342141748-1574249315-1264630062-1425
uid: root

Removing this account (the provenance of which was unknown) prevented the printing of this exception.
