I don't understand your question.   What does mail have to do with 
Samba?   Does your mail server use LDAP authentication?  Or do you want 
to use the LDAp server as an  central address book for your mail 
clients.  Either way, your  LDAP server should be able to support 
attributes  for both e-mail and samba requirements.
