Thank you all for the replies! I actually have been using the
dn.subtree syntax on each ACL, which works great. Right now, I am the
only admin of this system, so this is simple. However, as a few more
admins get involved, with their own suffixes/databases, I'd like to give
them their own db-xyz.acl file, included in slapd.conf for their
database. I trust them to not do anything malicious on purpose -- but I
also want to safeguard against them simply reading something from
google, and implementing a "access to * by * write", for example, and
having that affect RootDSE and Schema.
