Oscar, do you have a minute to post an example of how to use the nsldap API to look up passwords for a list of users? I'm thinking that it would be really simple to synchronize OpenACS passwords on a network by writing a procedure that periodically searches the directory (via nsldap) for each of the users in the database, and updates their password if it has changed. I haven't worked with LDAP before, so I want to be sure I'm going about this the right way.
