Questions[active-directory](ubuntu)

After upgrading my host to 12.04 I can no longer connect to Windows Shares in my AD (Active Directory) based network. I was able to do it previously using 11.10. I thought it might be an issue with the upgrade so I flattened my box and re-installed from scratch and I still can't connect.

When I use the Files>Connect to Server command, I am met with a constant password challenge when accessing any windows server using any known working network account.

I checked the logs on the windows machine to see if there are failed connections but there are none, yet 12.04 asks me for my password over and over as if my credentials were wrong.

Any suggestions?

So I work at a university using active directory, and in my office there are a few computers that I've set up, in Ubuntu 11.10, to log as an AD user.

In order to log in a person just needs to use the "other" user at login and use their university ID and Password. I've installed 12.04LTS on my personal computer, and I see that the "other" option no longer exists.

If I upgrade those computers who need AD login capabilities, will they have them?

I'm setting up an Ubuntu 11.04 server VM for use as a database server. It would make everyone's lives easier if we could have folks login using windows credentials and perhaps even make the machine work with the current AD-driven security we've got elsewhere.

The first leg of this was really easy to accomplish -- apt-get install likewise-open and I was pretty much in business. The problem I'm having is getting our admins into the sudoers groups -- I can't seem to get anything to take. I've tried:

a) usermod -aG sudoers [username]
b) adding the user names in several formats (DOMAIN\user, user@domain) to the sudoers file.

None of which seemed to take, I still get told "DOMAIN\user is not in the sudoers file. This incident will be reported."

So, how do I add non-local users to the sudoers?

I have installed likewise-open, but when I add an Ubuntu machine (10.10) to a domain, I am getting the following error:

Leaving AD Domain:   XXX.XX.XXX`                              
Error: Lsass Error [code 0x00080047]                       
1387 (0x56B) ERROR_NO_SUCH_MEMBER - Unknown error

Can someone sort this out?

Likewise-open shows me as being connected to domain. But how do I verify this?

• AD is managed by a Windows 2003 server.

I tried red's answer but it didn't work.

root@karthick:~# domainjoin-cli join XXX.XX.COM xxxxxxx
Joining to AD Domain:   XXX.XX.COM
With Computer DNS Name: karthick.xxx.xx.com

• Likewise-open Gui is already installed, but I am not able to leave the domain and re-join.

I searched google and i came up with this. Is that a problem? Or can anyone help me to debug the cause?

I am looking for instruction on how to configure my Ubuntu 10.04 box to allow samba shares access through Active Directory users and groups. I have joined the Ubuntu machine to my AD domain using Likewise-open, however when I enable 'security = ads' in my smb.conf I am getting access denied errors when trying to view shares in windows explorer. Any sugestions?
