Modify password

[Azeddine BOUKAIOU <boukaze@yahoo.com>]

hi all,

I want to modify user passord using LDAP; here is 
my

  /etc/pam.d/passwd file:

  auth sufficient /lib/security/pam_ldap.so
  auth required   /lib/security/pam_pwdb.so shadow MD5

  nullock
  
  account sufficient /lib/security/pam_ldap.so
  account required   /lib/security/pam_pwdb.so

  password sufficient /lib/security/pam_ldap.so
 
  /ACL in slapd.conf

  access to attribute=userpassword
         by dn="cn=admin,o=intranet.dz" write
         by self write
         by * none

  access to *
         by by dn="cn=admin,o=intranet.dz" write
         by * read


 when i type "passwd username", i get the message

enter login(LDAP) password: ( i enter the old
password)
new password: ( i enter the new one)
re-type password: ( i confirm it )

then i have this message 

password update failed : insufficient access
passwd : access denied

any idea will be appreciated
TIA
Azeddine
