Samba3 + OpenLdap classicupgrade problems - Administrator sambaSID != *-500

[Kamen Mazdrashki]

Hi,

I am playing with 'samba-tool domain classicupgrade' and I can't import
existing users - more specifically, the Administrator.

I have Samba3 + OpenLdap passdb backend.
Trying 'samba-tool domain classicupgrade ...' always lead me to:
Importing users

    raise ProvisioningError("User 'Administrator' in your existing

What are my options here?

Cheers,
