I looked this up and see what you mean.

The manpage seems to imply (to me at least) that the binddn is used when
checking the directory for ACL purposes. I guess I just misread that.

Darn. Let me ask one more time just so that I am totally clear on this.

Even with slapd-meta, there is no way to use openldap as a front-end to AD
so that I can do an anon. search against cn=Users to scan for names (cn, sn)
and email addresses (mail) to serve as an address book that can be
anonymously used?

In other words, my only option is to dump the values I want from AD into a
openldap databases on a regularly basis and have users just search the local
directory instead of serving as a proxy to AD.

Wow, I totally misread slapd-meta. I was thinking that with binddn this
would all work.

I saw that, but didn't follow up on it. Thanks for the information.
