From Jaunty Jackalope version of Ubuntu and now in the lastest release (Ludid, 10.4) it’s very easy to join your Ubuntu to an Active Directory. Where I work we have a huge Active Directory to centralize users, groups, computers and resources (far more than 3000 users).

Here I go to explain how to join an Ubuntu Lucid Lynx (10.04) box to an Active Directory server:

Before all take notice that your DNS are pointing to your corporative DNS and the client system-time is synchronized with the server time. To do this just issue the next command:

sudo ntpdate domain.of.your.ad.server.com

1. Install the likewise open AD authentication application with the next command: sudo apt-get install likewise-open
2. Register your Ubuntu system:

   sudo domainjoin-cli join name.of.jour.domain.com admin-user 

   (where name.of.your.domain.com is your domain name, and admin-user is a user account on the domain with permissions to add computers to it).

3. When prompted, enter the password of your adminstrator account. A dialogue box will appear asking for your domain name, enter your AD fully qualified domain name in upper case letters, i.e YOUR.DOMAIN.COM
4. Finally reboot.

Last  Thursday and Friday I was in Coruña attending to the GUADEC-ES, the most important event of GNOME and “hispanic version” of GNOME Users and Developers Conference.
It was my first event focused in GNOME and was simply amazing. I met a lot of GNOME Hackers and get the feeling that I’m in a collaborate with great community.

I enjoy all the talks but I have to highlight some of them.

• Git it done! by Mario Sánchez. I use git for more than 2 years but Mario gave us a glorifious crash course about it. You can find the slides [ES] in the next link: http://tinyurl.com/2wzqy6d
• Other of the talks that I prefer is “GNOME 3 para desarrolladores” (GNOME 3 for developers). Carlos Garcia Campos explain us the main differences between last GNOME libraries and what was done to achieve GNOME 3. Clean up !!
• The great discovery talk was “Vala, un lenguaje para Gnome 3.0” by Roberto Majadas. I heared just a little about Vala but Roberto with a lot of examples explain us the posibilities that Vala has to develop with a high-level language but with the benefits of optimization and speed of C language.
• And finally  ”cómo estudiar y participar en software libre sin morir en el intento” (How to study and participate in Free Software without die trying). Diego Escalante, developer of Epiphany, IMHO is the best speaker I have the pleasure to attend. The talk had a funny tone mixed with real experiences. Again you can find the slides here: http://people.gnome.org/~diegoe/slides/20100723_Coru%25C3%25B1a_Estudiar-y-participar.pdf

GPUL, coorganizers of this GUADEC, promised to make accesible all the videos recorded there. When this happen I’ll update this post to link them.

Conclusion: I recommend all to go this type of conferences cause you can learn a lot in just some hours and you’ll meet a lot of amazing people.

One of the reasons cause I love the GNU/Linux for developing is its easy and quick setup.

sudo apt-get install phpmyadmin lamp-server^

Dont forget the trailing ‘^’ char.

Quick post, quick solution. Isn’t it?
