Hello,
I'm testing samba4. I've setup a small samba3+ldap pdc, and then I
tried a classicupgrade, but I can't pass step 4 of the howto.
ubuntu@samba4:~/samba4$ /usr/local/samba/sbin/samba -V
Version 4.1.0pre1-GIT-899cdc4
ubuntu@samba4:~/samba4$ sudo /usr/local/samba/bin/samba-tool domain
classicupgrade --realm=example.com --dbdir=/root/samba
/root/samba/smb.conf

Skipping wellknown rid=500 (for username=Administrator)
Skipping wellknown rid=501 (for username=nobody)
Demoting BDC account trust for samba3, this DC must be elevated to
an AD DC using 'samba-tool domain promote'
Next rid = 1009
