[Samba] Problem adding smb accounts on 3.0.1/ldap

I am setting up a Samba 3 server with ldap support- packages from Debian
backports.org- but have run into a problem setting up the samba
attributes. If there is a user existing in the local /etc/passwd file then
smbpasswd -a correctly sets up the samba user in the ldap directory.
However, if I preload the posixAccount and other data for a user using an
ldif import then attempt to use smbpasswd to add the samba attributes it

Setting sambaSamAccount, sambaSID and sambaPrimaryGroupSID in the ldif
file seems to fix the problem but I didn't realise that this necessary.Or
is there a problem with smbpasswd?
