Ubuntu Servers :: Adding Server To Microsoft Active Directory Domain?
Mar 11, 2010
When i try to join my Ubuntu server to Microsoft Active Directory domain, i get the error message below.
Kinit failed: Clock skew too great Failed to join domain: Time difference at domain controller I know the reason is because of the time difference between my domain controller and the Ubuntu server. But what i want to know is that possible to join a domain without time synchronisation? Because my domain controller is working for another time zone, for another Country, so i can not synchronise it with my Ubuntu server.

The company I work for, as usual, is Microsoft-centric. I'm attempting to integrate my Ubuntu server into the domain to allow domain users to authenticate to the server and access file shares using Samba. Here's my current configuration:

i found samba as domain join service and print sharing, i am looking more then thisi have been looking any commercial or open source solution available as alternate of active directory. as we are all aware that AD infrastructure is highly complicated.the main issue we need to resolve is
- password policy for all users 90 days expiry
- use complex 9 chars policy
- assign permission/groups file/folder sharing

(This was posted at the end of another thread, where it probably didn't belong, so reposting here)I have Active Directory set up on one machine (and I can't really adjust the settings very much) and Ubuntu Server 10.04, which I would like to use as a client.I followed the directions at https://help.ubuntu.com/community/LD...Authentication, but when I get to
Code:
getent passwd
I don't see anything from the LDAP, and ssh'ing into the box from an LDAP/AD username certainly doesn't work.
In addition, I've attempted to use Webmin's LDAP Configuration module to configure it. I can connect to the server and can browse it with the LDAP browser with my settings, but the Webmin package doesn't recognize the users (which are organized in one of four Organizational Units (OUs) within the OU that I have as my Search Base) as users,

We have a small group of linux servers, currently with local logins. I want to eliminate the local logins and authenticate against the corporate AD. I've been looking at PAM - but winbind requires each machine to be added to the AD. This becomes a pain if we create new virtual or physical servers. Is it possible to have one server authenticate directly with AD, and the other servers authenticate against this server, which defers to the one server that is registered in AD?

We have a couple of Windows file servers that just share files. It is all they do. We'd like to use Ubuntu on two replacement servers allowing Windows XP and Windows 7 clients to access the files. Our network is active directory based due to Exchange and homegrown .NET apps, so it is important that active directory is used to authenticate the clients. Samba doesn't need to be a pdc or bdc, but provide pass through authentication.I understand that Samba can communicate with active directory through security-ads and security-domain.
Here are my questions to see if I should proceed:1) Folder permissions:If we move all our files to the Ubuntu server how do we set folder permissions and will we see the active directory accounts when we do this?2) Skipping ubuntu accounts: I know the domain and ads allow you to skip creating ubuntu accounts, right? If not, how do you keep the passwords synchronized?3) Easiest way? Is there a very easy way to pull this off that I've missed? My goal is to eliminate the Windows based file servers while ensuring the admin part of it is as easy as possible.To date I've been able to get the sharing to work with an ubuntu account mirroring the active directory account. I've been able to get Samba to talk to the pdc, but not successfully through domain security. ADS security was a complete cluster with winbindd

Attach a Fedora/RHEL/CentOS system to an Active Directory DomainBelow is a step by step outline of how to configure a Linux Samba fileserver to use an Active Directory domain for authentication and authorization in place of flat files. Note that this configuration has been replicated using Fedora 10, RHEL 5.3 and CentOS 5 since they all more or less share the same code base.me of the example server in this document is erver1.domain.forest.org, substitute correctly where appropriate. At the very least following packages must also be installed:
sambasamba-commonsamba-clientkrb5-workstationopenldap-clientsIt would be prudent to understand the underlying concepts of how Kerberos and Samba work prior to deploying this type of server. I find that SE-Linux will interfere with Samba services, particularly with winbind. I usually set SE-Linux to be in a permissive mode. It is possible to update the SE-Linux policies but that is outside the scope of this document, i.e you're on your own. In some cases I turned SE-Linux off since it was causing winbind to stop responding.
1. Set NTP to use the correct server for your Active Directory domain:shell> system-config-timeSet the primary NTP server to be your domain/forest NTP server2. Make backups of and edit the following system configuration files:a. shell> cp /etc/resolv.conf /etc/resolv.conf.bakb. shell> vi /etc/resolv.conf
nameserver dns_server1_ip_address
nameserver dns_server2_ip_address
search domain.forest.org

I've got a home server running Ubuntu Server 9.04 and several machines running Ubuntu Desktop (9.04 and 8.04) and Windows (XP, Vista and 7). Now what I want to do is to create a domain and directory server similar in function to Windows Server w/ AD and join my other machines to the domain, but am not sure where to start. I already have file shares with Samba but now I want to setup a domain.

I have a little nice Ubuntu server with 6x 1TB drives assebmbled into a RAID5 array. Recently SATA cable of one of the drives failed. So I ordered a new cable and ran the server in degraded mode for a few days. Like this:
Code:
/dev/md0:
Version : 00.90
Creation Time : Sat Sep 19 10:39:11 2009
Raid Level : raid5
Array Size : 4883812480 (4657.57 GiB 5001.02 GB)
code....
I'd like the 6th drive to be active, not spare, like before. Should I just wait for rebuild to be finished (it can easily take over 1 day)? Or should I add it somehow differently to be active immediately?
I'm not sure, but I think as I simulated failures unplugging one of the disk, after plugging it in again, the "failed" drive was active again and rebuilding was started as well of course. But it was 2 years ago, so...
The array works just fine for now - I can access files, etc. But I suspect, that in this state if another cable or drive fails, it won't survive anymore. Even after rebuilding is finished, but the 6th drive stays is still marked as "spare". Right?

I am the IT Manager at a research facility. We have a fairly unique network configuration in order to support all of the different projects we have going on. We have Red Hat, Ubuntu, Windows XP/Vista/7, Windows Servers 2003, Ubuntu servers, Red Hat servers, and even a few Netgear ReadyNAS and Buffalo Terastations. Over the last few years, I have been migrating all of my users and accounts to a single ACL list, which I chose to be a Windows AD 2003 server. 95% of my users work on Windows platforms and just use ssh tunnels to develop on our linux boxes.
However, i ran in to a problem with our Linux boxes not being able to symbolic link on my Windows 2003 file shares. Of course, this is a problem with Windows not supporting symbolic links. I know 2008 does support this feature, but given the economy and the budget restraints, we cannot afford to purchase the updates we would need, so now I am moving all of my shares to a Ubuntu 10.04 server using Samba. I have joined the server to my AD domain successfully, i can login using my AD credentials, and even assign ownership and group permissions using AD users/groups.
Here is my question.
I would like to keep the AD permission schemes intact. I have several shares that contain folders that have individual permission settings. For example, I have a /shared directory that contains about 50 different folders. Some of these folders I allow my users to write data to, some just read, and others I deny access to complete groups and just allow key groups to access (for example, personnel data should only be accessed by the Administrative staff).
Is there a way to make this work?
I can assign uid and gid manually per folder in Samba, but i would like to have the possibility to add multiple users and groups with permissions to folders, which I do not believe can be done with the standard chown commands. Currently, I can see the folder permissions from my Windows box, but when I try to edit the permission settings, it defaults back to full access. So my AD permissions are not being saved.

Since yesterday I'm fighting with OpenVPN on Ubuntu 10.04TLS and I can not cope with the authorization of users from Windows 2008 AD server. It looks like this: Published 93.159.XX.XX IP address the router and all traffic directed to the internal LAN IP 10.0.1.210. Customers who will combine the different platforms are Mac OS, Linux, Windows XP, 7, Vista. The whole domain is for Windows 2008.

This is the scenario: Active Directory Server = 192.168.0.1 Squid/Dansguardian Proxy Server w/NTLM Auth = 192.168.0.10 The Linux box has been integrated with AD and works fine. Users can authenticate automatically when login the AD or when they access the web through Basic authentication. That part is just fine.
But, when I add a new user, or change a users' primary group, I have to change the 'filtergroups' file in Dansguardian. I tried to make auto this process using the USERMAP and USERMAP2 scripts in [URL].. at the "Extras and Add Ons" section, but both scripts doesn't run properly in Ubuntu if they are not changed. I tried, following the instructions, but got a lot of syntax errors. So, I wrote a very simple script using 'net rpc' to retrieve all users according to the AD Security and Domain Groups. I created an output folder in dansguardian to dump the rpc outputs into files. And read the files to apply filtering groups.

Something that has been in the pipleline at work for a while is user-based web directories. Main PDCs are running Windows Server 2003 using Active Directory, ideally what would happen is that users have a web share under [URL].. - the server behind this would be Linux (either Fedora or CentOS).
What kind of configuration would be needed for Apache to make this possible? The way I have planned so far is to have the Linux box auth against the AD domain (possibly joined), with Apache setup to share local public_html folders. Not sure how I can get rid of the tilde from the start of the username, but it should be pretty easy.
