I don't think that can possibly be true. If you don't have a uri specified, you won't get any results. I just tested that on a system which is running a directory server.
Try this: $ grep '^[^#]' /etc/ldap.conf
I get:
base dc=private,dc=dragonsdawn,dc=net timelimit 120 bind_timelimit 120 idle_timelimit 3600 nss_initgroups_ignoreusers root,ldap,named,avahi,haldaemon,dbus,radvd,tomcat,radiusd,news,mailman,nscd,gdm,polkituser,rtkit,pulse uri ldap://directory.private.dragonsdawn.net/ ssl no tls_cacertdir /etc/openldap/cacerts pam_password md5
The nss-{key,cert}.pem may be used to bind at the following DN: dn: cn=nss,ou=Special Users,dc=example,dc=org
I don't think that makes any difference unless you specify binddn in /etc/ldap.conf
Setting ownerships to world readable, e.g.
...
doesn't change anything.
What about the permission on the directory /etc/nss?
All of those items must be readable by all users. The only file which can be restricted is an optional file referenced by rootbinddn in /etc/ldap.conf which is typically used if you require specific credentials to change passwords. If you use this file, non-root users still need valid credentials to bind and search the directory read-only.
You might be able to avoid giving users any access if you use sssd and nss_sss, but that's an unusual configuration.
The key to solving this problem is that all users of your system must have read access to all of the information that they require to bind and search in your directory server.
