[Samba] Migrating users

[Diego Martin Fernandez Fazio]

Hello, I need some ideas about one problem. I have 500 users with md5
password on a MSsql server that I need to migrate to a Samba server with
ldap. 
Is there any way to migrate or use those usernames and the md5 hashes? i
mean... may I use those hash for SMB? 
I know that openldap could use md5 but i m not sure if the samba+ldap
can use those hashes to autenticate the users.

Many many thanks and exscuse my bad english.

Diego.-
