Networking :: Active Directory Connection And Configuration?
May 13, 2010
I have successfully connected (and authenticated the user) from linux (Ubuntu) to Active Directory (windows 2003) using "Likewise Open".
1. at the login screen I have to enter "example.localusername" to login. how can I simplify the login so that the user can choose (click)the domain and just enter the username and password (like the login in windows) or make the domain the default.
2. how can I configure the default user profile? meaning, when the user login for the first time, I want to configure his profile. does it use the "/etc/skel" directory like the regular local login?

I've been working on building an LTSP server for diskless booting. I have a tftp server that's booting the system. I followed the steps on [URL] .... to build the LTSP server.
I had to make one change from the guide. I have a cisco router that's acting as the DHCP, I'm not very familiar with Cisco IOS so instead of playing with that, I decided to modify the default file on the PXE.
I commented the kernel append line and added the following instead
/srv/tftp/ltsp/amd64/pxelinux.cfg/default
Code: Select allappend initrd=initrd.img-3.16.0-4-amd64 init=/sbin/init-ltsp root=/dev/nfs rw nfsroot=10.0.5.99:/opt/ltsp/amd64 ip=dhcp
I'm mounting the nfs as a rw file system for now. I'm planning to make it read only once I have it working the way I want. In addition to this, I also chroot into the LTSP root and installed lightdm + mate. As I understood what I read, this would boot the environment on the diskless system. All of this seem to work correctly.
What I need to do next is to find a way to setup the LTSP clients to log in by authenticating on the active directory. I understand that the login account used by the LTSP client has to exist on the LTSP server.
I have successfully added the LTSP server as a worksation within the windows domain and I can log into domain accounts from the LTSP server but domain credentials do not work when using an LTSP client, I can only log in if I use an account that exists on the LTSP server. I wanted to know if there is a way to accomplish AD authentication.
Do I have to build an LDAP server on the LTSP server, sync accounts with the Active Directory to be able to log in with AD credentials?

I followed these steps to add a client to my active directory domain, everything is working as expected except that when a username has whitespace it creates a directory in /home with whitespace and gconf fail to access his config dir in the user's home. KDE also fails to start but I don't know what's failing yet. I found that the easiest way to fix these issues is to replace whitespaces by underline in homepaths so I changed the pam_mkhomedir source to replace the whitespaces and save it using the usermod command. It should work but is not... the reason is that I can't change the user data using the usermod because domain users are not in /etc/passwd.

I have set my Ubuntu 10.04 box with our Windows domain. I can see from "net ads info" that I am on the domain. I can also get the password and group info with getent.So far so good. But I have tried to configure pam basically by following this guide:http://www.ccs.neu.edu/home/battista...nbind/pam.html
Yet when I try to su or login as an AD user I just get and immediate "Unknown id: <userid>".I have had a look at /var/log/auth.log and there are no errors there.Can anyone provide some tips on debugging the pam configuration?

I am running the Ubuntu Netbook Remix and setting up our systems for Active Directory Domain Authentication. When I am hard wired in (ethernet), AD authentication works with no problems using the Likewise-Open software (installed through Ubuntu Software Center). What I want to be able to do is have people authenticate with AD with only a wireless connection. Has anybody done this before?

The scenario is I have a Windows Server 2003 Domain Controller which runs ADUC. I have created some security groups which I would like to apply to my network shares. The problem is, the majority of my network shares are based on Open Suse machines which, although are part of the domain, when trying to configure the shares using SMB, do not allow me to select the Active Directory groups. Any solution which will allow me to use ADUC security groups?

Most of the time when I go back to my computer, eth0 has disconnected if left overnight or several hours, and takes around 30 secs to reconnect to my router, finding it a little annoying as the reason I leave the computer on is for quick access to the internet.My computer is connected to the router via an ethernet cable.Used Mandriva and Windows XP on this same hardware for awhile and never came across this.How do I keep the connection to the router active?

I am trying to connect to my Company network through VPN. I use a Lynksys router which is most likely not the problem, as I can get the VPN and Remote Desktop to work from a WinXP Pro laptop connected to the same router. I have tried several RDC clients, none of them establish a connection. The VPN connection is active, I can ping and Traceroute to it , but I cannot get the RDC to work. The RDC should connect to 189.0.0.10 on the company network.

I'm having a problem with Active Directory and Share permissions that I cant seem to figure out. I used likewise-open to join my ubuntu server to a windows 2008 domain. Everything seems to be working fine. The problem is, the only way I can access the shares is if I CHMOD 777 the share directory. If I CHMOD 770, the Domain owner or Domain group member of the directory cant access the directory. Also, when creating a folder within the share, I need to set the directory mask as 777 in order to enter those sub folders.
Heres the share section from my smb.conf
Code:
[public]
comment = Ubuntu File Server Share
path = /srv/samba/public
browseable = yes
[Code]...

I am trying to sort out some issues following an upgrade from F12.
I have eth0 as the connection I want to use. Prior to the upgrade, this connection was enabled and active at boot.
Now, for some reason after the upgrade it has to be manually enabled at every boot - even though when I go the Network tool, Ethernet Device > General tab - "Activate device when computer starts" is checked.
At every boot time it is inactive.
In all the ifcft-eth0 files, the ONBOOT parameter is set to "yes".

I have a question regarding the configuration of Network Connection. My wired connection is fine right now and when I check the network connection applet, it display active information of eth0. However, when I click the Configure button, the Network Connection window appears but there's nothing in the Wired panel. Should there be a eth0 in that panel? I remember I had one before, but after I messed with some configuration of VPN, my network became unstable and I remove the Network Manager to try to solve the problem. Since then, there's nothing in my Network Connection window, though I can still connect to my router with eth0. Now even after I reinstalled the Network Manager, I still don't get anything.

I've very new to linux, so please excuse my ignorance. I am trying to setup a number of servers to authenticate against my Windows Server 2003 active directory. I have successfully done this with one computer (Dell Optiplex 755), but I can?t seem to get it to work with my servers (Dell PowerEdge R710). I am using Fedora 11. I have setup samba and pam and have successfully joined the network. Everything with winbind seems to be working properly and I can get all the user info, etc. When I log in with a local account, everything is fine. If I try to log in with an account from my domain through SSH, I see the message Code:/usr/bin/xauth: creating new authority file /home/apkelley/.XauthorityAfter that, nothing happens and it is as if I haven?t connected to anything. If I try to log into the actual server using the graphical interface, it starts logging me in, shows a blank screen for about a second, and then returns to the login screen as if nothing has happened.I would greatly appreciate any suggestions for how I might fix this problem or how to find out more information about the error.Here are my smb.conf and system-auth files:
/etc/samba/smb.conf
Code:

I've been trying to find a single set of instructions that define how to configure Fedora 12 to authenticate using Active directory without 100 steps (plus or minus) but difficult at best. I have about 12 Fedora 12 servers running as stand alone servers in a Windows 2003 network.
Can someone point me to a great set of instructions that can easily be replicated across multiple servers and a few workstations?

I'm actually a software developer, develop exclusively on Linux, and do know how to go about taking care of a Linux distro, so don't start telling me that 'sudo' isn't a sushi roll...
Question... I want to implement an Active Directory like authentication in a Linux-only environment. My office has approximately 15-25 local desktop PCs all running Ubuntu 10+ and one Ftp & SVN server running Ubuntu 10+.
Each developer has his/her own personal local account on his PC, and the shared PCs have different, local accounts for those developers. The FTP server has ONE (!!) account that everybody uses to access it, as does SVN.
The big picture is that I would like to install & configure a VPN server for remote developers. Before doing that, I'd like to find a way to unify the users across the network so that there exists only one UserX in the network.

I have AD DS installed on Windows Server 2008 R2. Also, I've got SLES 10.3 as NFSv4 server, which will allow remote users to mount their /home partitions. What I need, is NFSv4 w/Kerberos. As AD server already has integrated Kerberos server, I need SLES to authenticate in it.Everything works good, but when it comes to svcgssd service activation, I receive an error.Here's the log:

My boss has commissioned me with creating a new file server to replace a M$ server that is installed now. We want to go with Linux for many reasons, but one big thing we want to be able to do is still manage permissions using M$ type permissions from our XP desktop's rather than unix style permissions. How would this be accomplished on a CentOS box?

I have a freshly installed CentOS 5.4 box which I'm trying to get AD authentication working on. I have AD authentication via kerberos working for SSH, but when I try and have it work for SMB shares I'm getting an access denied error. What's even more odd is that when I tell pam to use winbind to authenticate SSH...it works just fine. Wbinfo -a username%password authenticates fine and getent passwd and group enumerates the AD users and groups ok. My smbd.log was throwing the following error "Failed to verify incoming ticket with error NT_STATUS_LOGON_FAILURE" but has since stopped for some reason, but googling this indicated I needed re-join the machine to the domain, which I have.
