HowTo: Authenticate Linux Clients with Microsoft Active Directory

Every IT shop has a mix of Windows and Linux system. Sometime you need to authenticate your Linux desktop system against Microsoft Active Directory service. You can save time, effort and IT infrastructure by sharing authentication server. This article explains how to setup the Linux desktop computers with Active Directory using Samba and winbind.

From the article:
Starting with Windows 2000, Microsoft moved from NTLM to Active Directory and its integrated Kerberos authentication services. Kerberos was considerably more secure than NTLM, and it scaled better, too. And Kerberos was an industry standard already used by Linux and UNIX systems, which opened the door to integrating those platforms with Windows.

Most Linux distributions come with several PAM authentication modules, including modules that support authentication to an LDAP directory and authentication using Kerberos. You can use these modules to authenticate to Active Directory, but there are some significant limitations, as I will discuss later in this article.

New Bulletproof X system for Linux / UNIX desktop

I was just wondering why this feature wasn't included in X from the day one. Ubuntu Xorg maintainer Bryce Harrington recently demonstrated the BulletProof-X feature that is planned for inclusion in Ubuntu 7.10:

This specification describes a new failsafe mode that will be used if X fails to start up. It will be in a reduced (VESA 800x600/256 or VGA 640x480/16) graphics environment running a single application (displayconfig-gtk) for configuring the graphics devices.

The goal of this specification is to eliminate the need for users to need to run apt-get reconfigure on the commandline. That approach is confusing and too technical for many users, so moving away from that will solve a key pain point for users.

This is useful if the user has changed monitors or graphics cards or X failed to detect your hardware. Linux based desktop system getting better and better everyday :)

Ubuntu Linux configure Viewsonic VG1930WM 19″ widescreen LCD for 1440×900 resolution

As I said earlier you need to tweak few things to run this monitor with Intel 810 or 845 based chip-set under Ubuntu Linux.

In order to use higher resolution install updated Intel i8xx, i9xx display driver. It is provided by a package called xserver-xorg-video-intel. This package provides the driver for the Intel i8xx and i9xx family of chipsets, including i810, i815, i830, i845, i855, i865, i915, and i945 series chips.

Replace driver by running the apt-get command. Open your terminal and type command:
$ sudo apt-get install xserver-xorg-video-intel

Now run ddcprobe command to get monitor VertRefresh values and HorizSync rate:
$ sudo ddcprobe | grep monitorrange

monitorrange: 24-82, 50-75

24-82 is your HorizSync rates and the second pair is your VertRefresh (50-75) values.

Next reconfigure xserver (X.org) video and monitor using auto detect feature:
$ sudo dpkg-reconfigure xserver-xorg

Set monitor resolution 1440 x 900 and others as per your requirement. Save the changes and reboot the system.

After login you can adjust screen resolution by visiting System > Preferences > Screen Resolution > Select desired screen resolution such as 1440 x 900 and save the changes.

New 19″ Viewsonic Widescreen LCD Monitor

Update: See howto configure Viewsonic VG1930WM 19″ widescreen LCD for 1440×900 resolution under Linux.

I’ve been thinking to post about this for a while. My old 15" CRT monitor died three weeks ago. I decided to replace the faulty monitor with the 19” ViewSonic and I'm glad I did.

The monitor works with Ubuntu Linux with little tweaks in X.ORG configuration file.. It is a remarkable monitor with a decent price tag.

I’m using 1400x900 screen resolutions and I’m quite happy with this display unit. Now I can view MRTG graph, monitor routers and server on a large screen. At work place I’ve 24” widescreen LCD monitor.

However my desktop system is quite old. It has Intel Celeron 1.7Ghz with 512+256 MB RAM. I’m thinking to upgrade this box with AMD 64 X2 5600+, MSI Diamond motherboard with RAID 5, SATA II, 2 Gig DDR2, and 512 MB graphics card.
