[Samba] Password question

[John Brown]

Suppose we were to set up a single Samba server with its own database of
users and passwords.  Users were authenticated by a Windows domain
controller for general access to the network.  However, we wanted to keep a
separate authentication logic for the stand alone server.  We would be using
OpenLDAP as the password backend.

How would the users change their passwords on this stand alone server?  Are
there any Samba or LDAP tools that could be used?  I have read the
documentation but I get the impression that the existing tools are designed
for Administrators to add and modify user info. on a domain controller.
