[Samba] import individual users from tdb to ldap?

[James]

Hi guys i was wondering if there was a way using pdbedit or elsewise to 
import only certain users from a passdb.tdb file into an ldap directory.

If there is i'd appreciate some help cause as far as i've seen it's 
either add a new user into the database and enter the password or 
migrate the entire passdb.tdb into ldap.
I already have some users info in ldap but not all of them because i've 
added users since migrating some of the data.

Any suggestions?
TIA
