[K12OSN] Migrating from Samba 2.2.8 to Samba 3

[Brian Chivers (Webmail)]

Has anyone managed to migrate from a samba 2.2.x PDC domain using a smbpasswd 
backend to a Samba 3 PDC with a OpenLDAP backend ?

I have setup a test server using the excellent (creep creep) smbldap-installer 
script and I can join machines to the new server without a problem and login 
but with over 500 machines I don't really want to have to visit each machine. 
What I'd like is to export the users / machine accounts from the current 
domain, and import it to the one.

I've set the SID to be the same as the existing system but when I move a 
machine from the old one to the new one or vice versa the machine complains 
that it's domain account doesn't exist.

I've tried using pdbedit -i smbpasswd:/root/smbpasswd_old -e ldapsam but I get 
this error

build_sam_account: smbpasswd database is corrupt!  username fred with uid 1060 
is not in unix passwd database!

Idea's please

Thanks
