There are two ways to use Likewise Open, likewise-open the command line utility and likewise-open-gui. This section focuses on the command line utility.

To install the likewise-open package, open a terminal prompt and enter:

sudo apt-get install likewise-open

The main executable file of the likewise-open package is /usr/bin/domainjoin-cli, which is used to join your computer to the domain. Before you join a domain you will need to make sure and have:

To join a domain, from a terminal prompt enter:

sudo domainjoin-cli join example.local Administrator

	 Replace example.local with your domain name, and Administrator with the appropriate user name.

You will then be prompted for the user’s password. If all goes well a SUCCESS message should be printed to the console.

After successfully joining an Ubuntu machine to an Active Directory domain you can authenticate using any valid AD user. To login you will need to enter the user name as ‘domain\username’. For example to ssh to a server joined to the domain enter:

ssh 'example\steve'@hostname

	 If configuring a Desktop the user name will need to be prefixed with domain\ in the graphical logon as well.

The domainjoin-cli utility can also be used to leave the domain. From a terminal:

sudo domainjoin-cli leave

Trouble Shooting

Here are some problems I ran into that I hope might help someone out there to solve

 

What I did to resolve this was to set the nameserver of the Ubuntu workstation to my Domain’s IP , to do this  I used this command cat /etc/resolv.conf

Nameserver 10.10.12.10 <—Domain Server IP

Nameserver 8.8.8.8  <—Google dns IP or what ever IP you want.
