ldap_modify: Server is unwilling to perform (53)

[<haiyi1@cox.net>]

Hi All,
 
I am a new LDAP user.  I just installed OpenLDAP 2.2.29 on Windows XP.  I can use LDAP Browser to connect but I can't make ldapmodify work.  Here is my command:
 
ldapmodify -D "cn=Manager,dc=my-domain,dc=com" -w secret -v -f  ldapmodify.ldif
 
then I get
 
ldap_initialize( <DEFAULT> )
replace objectclass:
         top
         organization
replace o:
         example.com
replace description:
         example corp
modifying entry "o=example.com"
modify complete
ldap_modify: Server is unwilling to perform (53)
         additional info: no global superior knowledge

 
It seems to be pretty simple but I could not find the problem.  
 
My ldapmodify.ldif file is:
 
 
dn:o=example.com
objectclass: top
objectclass: organization
o: example.com
description: example corp

dn:ou=Employees,cn=Manager,dc=my-domain,dc=com
objectclass: top
objectclass: organizationalUnit
ou:Employees
description:all employees

dn:uid=user1,ou=Employees,o=example.com
objectclass: top
objectclass: person
objectclass: organizationalPerson
cn:John Doe
sn:Doe
givenname:John
uid:user1
userpassword:password
ou:Employees
description:user1
 
 
 
My slapd.conf is:
 

#
# See slapd.conf(5) for details on configuration options.
# This file should NOT be world readable.
#
ucdata-path	./ucdata
include		./schema/core.schema

# Define global ACLs to disable default read access.

# Do not enable referrals until AFTER you have a working directory
# service AND an understanding of referrals.
#referral	ldap:/root.openldap.org

pidfile		./run/slapd.pid
argsfile	./run/slapd.args

# Load dynamic backend modules:
# modulepath	./libexec/openldap
# moduleload	back_bdb.la
# moduleload	back_ldap.la
# moduleload	back_ldbm.la
# moduleload	back_passwd.la
# moduleload	back_shell.la

# Sample security restrictions
#	Require integrity protection (prevent hijacking)
#	Require 112-bit (3DES or better) encryption for updates
#	Require 63-bit encryption for simple bind
# security ssf=1 update_ssf=112 simple_bind=64

# Sample access control policy:
#	Root DSE: allow anyone to read it
#	Subschema (sub)entry DSE: allow anyone to read it
#	Other DSEs:
#		Allow self write access
#		Allow authenticated users read access
#		Allow anonymous users to authenticate
#	Directives needed to implement policy:
# access to dn.base="" by * read
# access to dn.base="cn=Subschema" by * read
# access to *
#	by self write
#	by users read
#	by anonymous auth
#
# if no access controls are present, the default policy
# allows anyone and everyone to read anything but restricts
# updates to rootdn.  (e.g., "access to * by * read")
#
# rootdn can always read and write EVERYTHING!

Can someone tell me what the problem is?
 
Thanks in advance.
