for a development test bed I need to attach ANY linux machiene to a test AD Domain and do single sign on through it. Is there a Linux Distro that is easy to connect to AD?

I'm just looking for ANY linux not "the best" linux for use in AD. mostly looking for "super easy to attach to the domain" because all i need it to do is attach with the least fuss on my part. –  Arthur Ulfeldt Jun 11 '10 at 18:13

perhaps it was a silly question, this was stupid simple.

Ubuntu-10.04:

sudo apt-get install likewise-open
sudo domainjoin-cli join example.com Administrator

then ssh 'DOMAIN\username'@hostname and poof single sign on magic!

EDIT: today (June 2010) the likewise-open package is missing a dependency on psmisc so you have to run this first:

sudo apt-get install psmisc

if you already installed likewise-open then:

sudo apt-get purge likewise-open
sudo apt-get install likewise-open

EDIT1: need to add the AD DNS server as the hosts dns server first, and set the hostname.
EDIT2: need to make sure the reverse dns is correct.

CentOS, just open a terminal and type "setup" - then follow the instructions

On RHEL or CentOS 4 or newer the following command will reconfigure the auth system and join AD. You can remove the flag for PAM /etc/security/access.conf if you don't want to configure it but I find that not everyone with a valid AD account should be allowed onto every host, only members of certain AD groups. I believe there is also a flag to configure winbind to allow disconnected authentication, for laptops and such which need to log in when not on the network.

sudo /usr/sbin/authconfig-tui \
 --enablewinbind \
 --enablewinbindauth \
 --enablemkhomedir \
 --enablepamaccess \
 --enablelocauthorize \
 --smbsecurity=ads \
 --smbrealm=DOMAIN.COM \
 --smbworkgroup=DOMAIN \
 --smbservers=dc.domain.com \
 --winbindtemplatehomedir="/home/%U" \
 --winbindtemplateshell="/bin/bash" \
 --enablewinbindusedefaultdomain \
 --kickstart \
 --winbindjoin=DomainAdminAcct

Actually any Linux distro with a current Samba install should be able to be joined to a Windows domain. As mentioned Likewise on Ubuntu makes it extremely easy to get it up and working but I found that it worked best if I didn't have Likewise AND Samba installed otherwise they tried to fight one another.

Samba would be a more involved installation process as Likewise appears to be solely a NSS plugin of sorts while Samba adds the whole kitchen sink along with it allowing file and printer sharing to be made available.
