Hi,
in my opinion this is not a security issue, but a feature compliant to
the ldap rfcs. A server should expose a minimal set of information about
itself, eg supported controls, saslmechanisms, namingcontexts even to
anonymous users - and many applications rely on this.
If you really want to turn this off, you need to modify the aci for the
"dn:" entry

LDAP allows null bases
Risk:High
Application:ldap
Port:389
Protocol:tcp
ScriptID:10722
Summary:
It is possible to disclose LDAP information.
Description :
Improperly configured LDAP servers will allow the directory BASE to be
set to NULL. This allows information to be culled without any prior
knowledge of the directory structure. Coupled with a NULL BIND, an
anonymous user can query your LDAP server using a tool such as
'LdapMiner'
Solution:
Disable NULL BASE queries on your LDAP server
