Problem with netscape

[Michele Cerioni <michele@protocol.it>]

I configurated openldap as address book of my net.
slapd.conf


include         /usr/local/etc/openldap/schema/core.schema
include         /usr/local/etc/openldap/schema/cosine.schema
include         /usr/local/etc/openldap/schema/inetorgperson.schema
include         /usr/local/etc/openldap/schema/nis.schema
include 
/usr/local/etc/openldap/schema/redhat/rfc822-MailMember.schema
include         /usr/local/etc/openldap/schema/redhat/autofs.schema
#include /usr/local/etc/openldap/schema/redhat/kerberosobject.schema
database        bdb
suffix          "dc=protocol,dc=it"
rootdn          "cn=Manager,dc=protocol,dc=it"
rootpw          secret
index default   eq
index objectClass,uid,uidNumber,gidNumber eq
index cn,mail,surname,givenname eq

access to attr=userPassword
        by self write
        by anonymous    read
        by dn="cn=Manager,dc=protocol,dc=it" write
        by *    compare
access to *
        by self write
        by dn="cn=Manager,dc=protocol,dc=it" write
        by *    read

----------
this is my first file ldif  used to populate the directory

dn:             dc=protocol,dc=it
objectclass:    dcObject
objectclass:    organization
o:              Application Server
dc:             protocol

dn:             cn=Manager,dc=protocol,dc=it
objectclass:    organizationalRole
cn:             Manager

dn:             ou=people,dc=protocol,dc=it
ou:             people
objectclass:    organizationalUnit
objectclass:    domainRelatedObject
associatedDomain: protocol.it

dn:             ou=contacts, ou=people,dc=protocol,dc=it
ou:             contacts
ou:             people
objectclass:    organizationalUnit
objectclass:    domainRelatedObject
associatedDomain: protocol.it

dn:         cn=pippo,ou=contacts,ou=people,dc=protocol,dc=it
cn:             pippo
mail:           pippo@protocol.it
uid:            pippo@protocol.it
givenname:      aaaa
sn:             ssss
objectclass:    person
objectclass:    inetOrgPerson
objectclass:    top


With Outlook I can search in LDAP server, instead with netscape I get 
the message

LDAP initialization problem
Error code 2: Protocol error

The configurations of Outlook and Netscape are the same!



Where Do I wrong?
