Need help to change ldap password from client side

[sivakumar R <sivjimails@gmail.com>]

Dear All,

I've recently configured a LDAP Server, I am facing a small problem when i'm trying to change my password from client side by giving the command "passwd". It is giving the following error in terminalÂÂ 

Changing password for user ****.
Enter login(LDAP) password:
New password:
Retype new password:
LDAP password information update failed: Insufficient access
passwd: Authentication token manipulation error


Also in /var/log/messages it is showing the following error message

Jan 24 15:43:57 mail passwd: pam_ldap: ldap_modify_s Insufficient access
Jan 24 15:43:57 mail gnome-keyring-daemon[6329]: gck_module_new: assertion `funcs' failed

Also this is my ACL configuration details of /etc/openldap/slapd.conf


access to attr=userPassword
Âby anonymous auth
Âby self write
Âby * none
access to * by * read

Please help to resolve this


Cordially
