You *have* to get ACLs working. You can't possibly use OpenLDAP (in
production, at least) without some quite complex ACLs.

'man ldapsearch'. ldapsearch without -x assumes that you are asking for
SASL support that you have configured in slapd.conf, and you haven't. The
fact that you get the same results for root or a non-root user doesn't
have anything to do with the Unix user that you are logged in as; slapd
doesn't care about the Unix )posix) user. It only cares about users in DNs
that you feed it.

Yes. I have to agree with Craig White here (I usually do ;) LDAP for me is
the be-all and end-all. i use it for across-platform authentication in
production for *everything* It is the corner stone to all services that my
users may use. If an application doesn't work with it, then that
application is useless to me. Examples of apps that use a single login and
password at one site I administer (runs 3 servers under RHAS3 using the
same LDAP DSA) are postfix smtp, Courier IMAP, Linux Terminal Server
Project, Pykota print quota admin, ssh and a Samba PDC. To be able to
master the LDAP part thoroughly, I chose to use source code and subscribe
to the 4-5 mailing lists dealing with this. Craig does the same.
Get samba working without LDAP first, then make sure you master every
possible aspect of openldap and are completely confident with it. Then you
can adapt what you've done to Samba.
