Change password on Ubuntu client using LDAP Authentication

Question

I've setup a computer lab running Ubuntu 14 clients and an Ubuntu 14 server.

The clients are successfully logging in using credentials provided by Open LDAP. I used this guide to configure the clients - https://help.ubuntu.com/community/LDAPClientAuthentication

I would like to enable each user to change their password at the client.

I've tried the usual ways to change password -

1. Through System Settings, but need to login as root user to "unlock" User panel
2. Through terminal - passwd. I get "Authentication information cannot be recovered"

Thanks in advance for any help.

Answer 1

In client system edit file

/etc/pam.d/common-password

and remove the word auth_key.
