I have a ldap server on CentOS, 389-ds. I configured the client, ubuntu 12.04, to authenticate on that base and it works very well. But it don't gets the password policies from server. For example, if i set the policy to force user to change the password on first login, ubuntu ignores it and logs him in, always.

How can i setup the client to get the policies?

Here are the client files:

/etc/nsswitch.conf

passwd: files ldap 
group: files ldap
shadow: files ldap
hosts:          files mdns4_minimal [NOTFOUND=return] dns mdns4
networks:       files
protocols:      db files
services:       db files
ethers:         db files
rpc:            db files
netgroup: nis
sudoers: ldap files
