Authentication w/ Eudora & other clients

["Dean Gibson (Mail Adminstrator)" <postmaster@ultimeth.net>]

I have OpenLdap 2.0.21 installed and working, including SASL authentication with ldapsearch and ldapmodify, which work as expected, accepting and rejecting users appropriately.  However, I have been unable to get the following LDAP clients (all of which supposedly have authentication capability) to obtain lookups from the LDAP server unless I specify:

access to * by * read

Here's the list of LDAP clients:

Eudora Pro 5.1;  free download at http://www.eudora.com

Softerra LDAP Browser 2.3;  free download at http://www.ldapadministrator.com/download/download.php

Java LDAP Browser/Editor 2.8;  shareware download at http://www-unix.mcs.anl.gov/~gawor/ldap/

Here's my actual access directives:

access to dn="^$"
                by *            read
access to dn=".*"
                by users        read
                by anonymous    auth

Has anyone gotten these clients to work successfully with SASL authentication?
