domain samba3upgrade fails

[Greg Dickie]

Hi,

  I'm trying to upgrade an LDAP backed samba3 domain to samba4 using the
samba-tool domain samba3upgrade procedure. It seems to go quite well
until it starts to import users. At that point I get this:

Group already exists sid=S-1-5-21-743015788-4153008934-1122164905-514,
groupname=Domain Guests existing_groupname=Domain Guests, Ignoring.
Importing users
Failed to modify account record CN=auser,CN=Users,DC=domain,DC=local to
set user attributes: Unsupported critical extension

691, in upgrade_from_samba3
    s4_passdb.add_sam_account(userdata[username])



This seems to be an error returned from the builtin LDAP server? Any
idea what the problem could be?

Thanks alot,
Greg
