Thanks, Nigel. I'll give it a shot today and see what happens.

The specifics are totally dependent on your slapd.conf ACLs. The order of
the ACLs is highly significant and just inserting a new ACL can render later
ACLs useless. Getting this one wrong can render your LDAP authentication
scheme useless, or wide open for anyone to read your entire password
database.

What you need is something *like* this, fairly high up in the ACL tree:

access to dn.subtree="dc=your root" attrs=userPassword
         by self write
         by dn="uid=<rootbinddn>,dc=your root" write
         by anonymous auth
         by * none


One way to test it is to try changing a users password using ldappasswd,
binding as that user with their existing password. ldappasswd is part of the
openldap-client package.
