[Samba] Migrating: tdb to ldap (Samba Classic)

When I migrated from TBD to LDAP I had to write some perl scripts to
reformat the data exported from TDB into the correct LDAP
structure. The smbldap-migrate tool did not seem available with my
distribution. Moving to Samba AD had not been an option because
this was still Samba 3 (and AD server support in Samba 4 was still
experimental), and I also need LDAP backend for non-samba
services. Samba AD didn't support domain trusts (I still
think it doesn't completely support them) which also was a deal breaker.
