LDAP error "ldap_bind: Invalid credentials (49)"

Dear Server professionals

I run in an error "ldap_bind: Invalid credentials (49)" eatch time I try to import a ldif file. Below I wrote my slapd.conf file and my command I use.

#
# Disallow clear text exchange of passwords
# disallow bind simpleunprotected
#
# 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:
# Allow read access of root DSE
# 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 *
# by self write
# by users read
# by anonymous auth
#
# if no access controls are present, the default policy is:
# Allow read by all
#
# rootdn can always write!

# Some settings are maintained in slapd_macosxserver.conf,
# which is updated by Server Admin. Put your own changes in
# this file.
