Yes and No. You can manually add the required attributes from
samba.schema with ldapmodify or something similar. You cannot convert
the md5 hash, hashes are one-way that's the point of having them.

You need all three attributes (userPassword, sambaLM..., sambaNT...),
samba can update the unix password if users change the password from
windows clients (sync ldap password = yes, OTOH). If you don't want to
have new passwords you'd need access to the cleartext passwords or
require users to change their password and intercept this to get the pw...
