Ubuntu Security :: File Server With Users Of Active Directory?
May 26, 2011
I want to create a shared folder in a ubuntu sistem but I want to know if I can get access to some users of my domain active directory windows 2003 server?If I can, I would give that security in some of the subfolders of that shared folder as explained at the example:XAMPLE:
Backups (all have access and it's shared)
Mail of Charles (Can only have access Charles that have an account on domain)
Mail of John (Can only have access John)
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:
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
I am using openSUSE 11.2 with active directory for authentication. I configured it using the Window Domain Membership YaST2 module and I can login successfully (although unreliably). The problem is that I need the UID and GID of the users on my computer to match the UID and GID assigned by Active Directory. Currently it just assigns UIDs and GIDs starting at 10000, which is completely different than the UID and GID used by Active Directory and by other Linux computer runs by the school (those use CentOS). Does anyone know how to get my openSUSE computer to assign UIDs and GIDs from Active Directory?
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. Uploader authLDAP module, but I still can not connect, that is, not after entering the username and password from the W2K8 domain does not log
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.
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.
I have running on RHL enterprise 4. I want to configure squid users to authenticate against windows 2003 active directory. How do I go about from scratch
I have configured squid with AD. It is working fine. Now I want to use dansguardian with squid for web filtering on group bases, what should I do. What configuration i have to do in squid for dansguardian and all my users in AD also authenticate with dansguardian and also how I use dansguardian.
I'm tasked with creating a base image of ubuntu (one for server, one for workstation) that is locked down and has all the fluff taken out (naturally workstation will have more fluff left in it than server). Task list looks about like this:
1. Create list of deb packages "allowed", write script to list/uninstall everything else.
2. Hook the logins into either enterprise kerberos or Active Directory (yuck).
3. Write scripts to check things like setuid/setguid, disabling su, checking sudo permissions, configure iptables, etc.
4. Use a scanner to scan the system from outside the system (was thinking of using backtrace).
5. Custom-compile the kernel to strip out all the unneeded modules.
Before embarking on this awesome task I figured I'd check with you guys to see if you know of some resources that would make this task easier/quicker. I'm sure someone out there has already headed down this branch.
PS My boss *loves* ubuntu and isn't to keen on going with a deb (or other) distro that is already "security trimmed" without some serious convincing. I'm sure there are some out there, and if you want to pass along a couple for consideration, I'll check them out, but no guarantees he'll let me use it.
Which package I need for install AD for linux ubuntu server 9.10 could you help explane my in example, which package i need install in server and which package i need install in client.
I need to install FTP Server in CentOS and it has to integrate with Windows 2003 Active Directory. Users should use their Active directory Credentials to upload or download files in FTP Server.
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 would like to set up Some kind of windows user manager in an ubuntu sever. The windows network is already set up. I've scoured the net for hours and found nothing.
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.
I would prefer to use a linux server for authentication but I will need the same configuration features.I have been looking for a good guide to setting up CentOS as an alternative to Active Directory, but have not found one yet.The features I want to see.
1. works with Windows clients. 2. Network Home folders (does not neessisarly need to hold profile information) 3. Logon scripts for clients. 4. shared printers 5. shared folders. 6. can log linux boxes in with the same credentials and logon scripts.
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?
(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,
I have a Ubuntu 9.10 desktop, with an external HD shared via Samba, with some users and folders on it. I have another computer on the network running Winblows Server 03', handling Active Directory (that I am still setting up and testing before any serious implementation.) I've been testing GPOs I am building on an XP SP3 virtual machine that is running off my Ubuntu desktop as well, that I joined to the AD domain.
However, the Domain Controller doesn't have a very big hard drive, and I'd like to take advantage of having 930GB free on this external hard drive for roaming user profiles, especially since I backup all of the drive contents every week. This would simplify a lot for me. What would you recommend is the best way to go about setting this up with my Samba configuration? I have a feeling /media/Slave/UserProfiles permissions will get somewhat complex.
I have around 12 users, with their profiles present on a Windows 2003 Active Directory and I would like to migrate to an open source free alternative.Could you recommend any alternative that supports the migration of user files from Active Directory?
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?
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.
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.
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?
I'm trying to get our linux servers to use Active Directory (AD), and have gotten our linux (RHEL 5) server to fetch users and groups from AD. Now I'd like to add computers (and groups of computers) to AD, and have our linux boxes make use of this info. Does anyone know how to get our linux-boxes to understand computers and computer group objects on AD?
