Ubuntu 9.10 Authentication

Introduction

The following details the setup of Ubuntu 9.10 Karmic Koala as a desktop to authenticate users against SME. The method has been tested using Ubuntu installed in a VirtualBox virtual machine on a Windows XP host.

Install Ubuntu

Download the Ubuntu .iso and install. When prompted for a user name give a non-SME user such as administrator as this first user effectively becomes a local user with sudo root access. Complete install, login and apply all updates.

Additional Packages

Use the package manager to install additional packages

auth_client_config
winbind

Authentication Modifications

	Warning:
	Altering the pam system authentication files can seriously effect your ability to login in to the system. Take a backup of the /etc/pam.d directory and /etc/nsswitch.conf. Have a live CD available to give access and re-apply the backup files if you make a mistake and/or get locked out

Open a Terminal cli and change to root privileges

sudo su

Using your favourite editor, open /etc/nsswitch.conf and find the hosts: line. Change it to

hosts: file wins dns

Change to the auth-client-config tool profile directory

cd /etc/auth-client-config/profile.d

Using your favourite editor create a new file called acc-sme and enter

[sme]
users: compat winbind
passwd: compat winbind
shadow: compat

Save and apply the pam authorisation changes

auth-client-config -a -p sme
