CentOS 5 Server :: Active Directory 2003 R2 Integration?
Jul 29, 2009
I was working to integrate Centos 5 and AD 2003 R2, this is my set up Windows side:
1. Install Identity Management for Unix, (Windows R2 already includes the Unix attribute not entirely necessary to install IMU, but it makes easier to configure the attributes from ADUC, when IMU is installed the Unix attributes TAB is shown in the user properties)
2. Configure the Unix attributes for every user account that will be authenticating from centos.
3. Create an user account to be used as a proxy for ldap, a regular user would be enough. Password never expires.
4. Create a computer account for every centos host; assign this computer account as pre-windows 2000 account.
5. Assign a value of 4128 to the user account control property for the computer account.

My all production PC r running under ADC windows2008 server. Recently I implement a file server in CentOS 5. Now I want to integrate Samba (File sharing) using Active Directory so that all access permission to file server comes from AD's permission.

First, I'm extremely green with linux. I'm trying to configure my CentOS 5.2 box to authenticate my SSH users with my Active Directory. What would be the best way to go about doing that? I've configured Winbind and joined it the the domain but I'm not able to login locally or SSH with an AD account. I'm not sure where to go from here. Also my users will not be accessing any file shares on this box, SSH only.

I am trying out few stuff with Linux and Windows. I have a 'Postfix' mail server on CentOS 5.5 with 'dovecot' and 'squirrel' (webmail) working fine. I am just wondering, how can I create bulk mailboxes on CentOS 5.5 (for postscript) so that the the users can access their mail from the browser (squirrel mail)?
How can I integrate with Active Directory? I am also looking for techniques to automatically create bulk users (for example 100 users) on Active Directory with a default passwords (or random passwords if possible) that integrate with Postfix.

2. Network Home folders (does not neessisarly need to hold profile information)
3. Logon scripts for clients.
4. shared printers

okay so we have multiple servers running CentOS and multiple people who need access to these machines for various tasks. i would like to be able to use the credentials from Active Directory (running on server 2008) to give them access to these servers without having to go through each server and add these people into permission groups. basically a single sign-on for all of these servers depending upon what permissions were granted in Active Directory. how do i go about doing this?

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.

I've configured kerberos authentication on my centos 5.2 box. When I kinit with a username in AD and not on the centos box, I get a TGT. However, I cannot log into the centos box as any of the AD users. This is probably a stupid question but do I also need to create the account's on the centos box that I have in AD? If so, does that mean i can then use pam to authenticate users on my cyrus imap process running on the centos box?

I've been looking for alternatives to Active Directory with Centos mainly SAMBA and OpenLDAP. I have worked with SAMBA and I know I can create a PDC and make clients join a domain but how about enforcing Group Policy?... is this possible with SAMBA or OpenLDAP/LDAP?

I have just installed the 32bit and 64bit versions of CentOS 5.5 and was wondering how I can add these machines to Active Directory for authentication. I've done this in the past with CentOS 5.4 using the GUI and everything worked just fine but now need to do everything from the command line.

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 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:
/usr/sbin/rpc.svcgssd -f
ERROR: GSS-API: error in gss_acquire_cred(): Miscellaneous failure - No principal in keytab matches desired name

I have a squid server currently running with basic authentication. This is a must because we constantly have different people using different machines but the rules must be set per user, not per machine.
We also have a lot of users coming and going. So every time a new user comes to the office I have to manually create a user for him so he can authenticate.
Anyway.. We do not have any windows servers so no Active Directory. But I need some solution to pass the windows login to Squid.
First question: It seems I am using NTLM currently for samba as the person can map their home directories on their windows box withuot authenticating. Why can I not use it for squid?
Second question: Can I make my Centos server into an AD server?

(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,
