samba - Jun 2016 - Classicupgrade of 4.1.17 error: "list index out of range"

I'm trying to upgrade to AD from a Samba 4 PDC with openLDAP (on Debian 8).

I'm stuck at this very unhelpful error:

    # samba-tool domain classicupgrade --dbdir=/usr/local/samba.PDC/dbdir/
    --use-xattrs=yes --realm=ad.mydomain.tld --dns-backend=SAMBA_INTERNAL

         urls = samba3.lp.get("passdb

Any ideas on how to fix it or at least find some better clue?

    # samba --version

Thanks.

could you please post the "passdb backend" line of your 
/etc/samba/smb.conf.PDC file? (or even better post the whole file)?

Thanks,

Denis

I retried after deleting all machines, groups and people from LDAP, to see if
the
problem was hidden in there. But apparently not, and I still get the same error.

After adding --debuglevel=10, I see lots of debug messages during the LDAP
search,
but nothing more after that:

    # samba-tool domain classicupgrade --debuglevel=10
    --dbdir=/usr/local/samba.PDC/dbdir/ --use-xattrs=yes --realm=ad.mydomain.tld

--option="bind
    interfaces only=yes" /etc/samba/smb.conf.PDC
    ...

    The connection to the LDAP server was closed

Solved. The fix was to replace

     passdb backend = ldapsam

with

     passdb backend = ldapsam:"ldap://localhost"
