Environment

Solution
Installing the following packages. During the installation you should set the data referent with the OpenLdap system.
sudo apt-get update
sudo apt-get install libpam-ldap nscd sysv-rc-conf
Modifying the file /etc/nsswitch.conf in order to search the users into OpenLdap directory. You must add ldap at the end of each line.
passwd: compat ldap
group: compat ldap
shadow: compat ldap
Removing the text use_authtok from the following line located in the file /etc/pam.d/common-password. The line should stay like this:
password [success=1 user_unknown=ignore default=die] pam_ldap.so try_first_pass
Adding the following line at the end of the file /etc/pam.d/common-session.
session required pam_mkhomedir.so skel=/etc/skel umask=0077
Activating the module libnss-ldap by typing:
sysv-rc-conf libnss-ldap on
Reboot the operating system
sudo reboot
Done!!! Ubuntu 14.04 client has been configured!!!
