Ubuntu Servers :: Samba As Domain Member Server Authentication
Apr 20, 2010
I've been working for hours with Samba on Ubuntu Server 9.10 (Samba version 3.4.0), trying to get it setup simply as a fileserver that performs authentication to an NT 4 server (yes, I know, old and out of date). After much struggling, I finally realized that my configuration *was* working when the clients connecting (from XP, and Win2k clients, mostly) were actually joined to the domain (where the PDC is the NT 4 Server) and logged into the domain.For various reasons, many of the Windows clients at this location don't actually log into the domain, even though they have login/passwords that are valid users on the domain and they'll typically have some drives mapped to the PDC.
By the way, I have this working on another Linux box running Samba 3.0.28, so I'm sure it's possible, I'm just lost as to how to do it.I can provide plenty more information if it would help diagnose the situation. Does anyone have an idea of how I can get this to work? I'm sure it's possible, since the exact scenario worked in a recent version of Samba.
I follow those guides: [URL] and [URL]. I join the domain, I can test the user [root@osra ~]# wbinfo -a mbottalico% plaintext password authentication succeeded challenge/response password authentication succeeded
[root@osra ~]# wbinfo -g utenti wins dhcp users dhcp administrators computer del dominio controller di dominio getent passwd and group ok without "DOMAIN+" kinit e klist ok.
I can browser the samba server, but I can enter on "temp", but not in "test" (access denied) [root@osra ~]# smbclient \\osra\test -U administrator Enter administrator's password: Domain=[DOMAINSHORT] OS=[Unix] Server=[Samba 3.3.8-0.52.el5_5.2] smb: > ls NT_STATUS_NETWORK_ACCESS_DENIED listing * (I noticed only writing this message)
[root@osra ~]# smbclient \\osra\tmp -U administrator Enter administrator's password: Domain=[DOMAINSHORT] OS=[Unix] Server=[Samba 3.3.8-0.52.el5_5.2] smb: > dir ..... 53488 blocks of size 2097152. 49908 blocks available smb: > q 0 blocks of size 0. 511 blocks available .....
I have Windows 2008R2 Server acting as Domain Controller for Windows7/XP clients. and CentOS 5.3 Installed configured as Samba Server, I want to make it as ADS member server so any user to login to any machine, and be able to access their Samba share.
I have a samba server for company file shares but we do not use domain services or active directory service. Each workstation is its own standalone system. (And we want to keep it this way.) I would like to have some centralized authentication though, and it looks like Kerberos will provide that. After a lot of searching though, I can't find any instructions for setting up samba to authenticate users using kerberos without an ADS (active directory service) or domain. Is this possible?
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 don't know if the problem is the way I create my shares on the Domain member, but here is the way I've configured my systems. My systems are home based, and though the topology may be all wrong, it's set up this way only for test purposes. I love to get things up and running.I've already had a Domain Member running under Samba 3.02xx (Centos), but I'm having problems under Ubuntu and Samba 3.40
Server call Citadel is a VMware Server. I've got 3 virutal machines on this Server, 2 Ubunt 9.10 servers, and 1 Windows XP pro. One of my virtual servers is call Winserver, a Samba PDC server using TDBSAM as it's backend. Configured and working well. I have a share that I can access.On my Windows XP, I'm a domain member, able to access my WinserverServer share "Linux Doc", but when I try to access my domain member, it keeps asking me to login.
Making a Samba Server with LDAP authentication. Will post as I go along. Found these sources, anything/hiccups I should know before jumping in? Figure would follow the official documentation then check the others for comparative errors.
I have configured NIS, DNS, NFS and DHCP servers at my home network. I can easily authenticate another Linux machine to these servers and make that machine as a client and also users can locin using the automounter. My Question is, is it possible that by using the same setup I can authenticate a windows Xp machine and make it as a client, and also users can login using the passwords that I have provided on my NIS server?
Does anyone have a link to a tutorial on how to set up a DHCP server and SAMBA as a windows domain controller? I can't really find good detailed guides by searching google.
i need to allow window domain controller user to use file share of linux.windows DC user can see the share file and directories of linux file server but not able to access.
below is brief--
I have a Linux machine which is on my network but not on my domain. I have configured SAMBA FILESERVER for file sharing purpose. I have a Windows XP PC which is on the domain(windows server) that I am trying to connect to a share on the Linux box. I supply my credentials but regardless of which login I use I always get Logon Failure. I have created an account on the Linux machine with the same user name and password as my domain account but so far no luck. Can I connect from a domain PC to a non-domain Linux box? Is there something else I should be checking?
I have to rename a group of machines in my little samba domain (tbd backend) but there is an ugly bug that makes this impossible. have set 'rename user script' variable corectly, also checked all configurations.When i change computer name in my windows box, it shows an error saying something like "Error calling remote procedure"Looking on server side, username for the machine gets correctly changed in /usr/passwd, and also in samba database.But samba log says:
=============================================================== [2009/10/08 11:10:32, 0] lib/fault.c:fault_report(42) INTERNAL ERROR: Signal 11 in pid 11052 (3.0.33-3.7.el5_3.1)
I am practising setting up a small network using UBUNTU as a PDC through SAMBA to service xp clients.
I have sucessfully setup DNS on the Ubuntu server using Bind9 and can nslookup from both the client and the server by FQDN and can also ping ipaddress.
I have setup a basic smb.conf file however when I try to add the xp client to the domain I get an error message saying a domain controller for the domain could not be contacted.
I have disabled the firewalls on both the server and the xp client and still get the same error message when trying to join the domain. I've checked my network settings on the client, its set to use a static IP address and the DNS server and WINS server are set as my Ubuntu Samba PDC address.
I haven't been able to see anything odd in the smb.conf file that might cause this issue. I can connect directly to the shares using the samba network account that I created by going to start run and typing in the unc path.
Not sure what the cause of this issue is, I thought it might be a DNS issue on the client. One odd thing I noticed is that when I do nslookup using just the server name and not the FQDN i get a message in dos saying that the default server cannot be found but says that the server name for the [ipadress] cannot be found. It does list the correct ip.
I'm not sure what is causing the problem of stopping my xp client from joining the Ubuntu Samba PDC. I'm using UBUNTU server 10.04.
My samba domain controller will not serve up scripts upon login, and acts very slow when not connected to the Internet. Also, network browsing from windows boxes shows no computers on the network once all this happens. Once the net connection comes back up, everything is fine.
Domain server:
Ubuntu 10.04.2 LTS Samba 3.4.7
Router: Smoothwall Express 3.0-polar-i386 3.0 (update6). Router is set up as DHCP, and appears to be serving up normal IP's when the Internet connection goes down. I can ping the domain server at its normal IP when the connection goes down.
I've been configuring a PDC using samba I used this tutorial url as reference. It seems all went well during the installation and configuration not until when I try to join a windows machine to the domain.
Scenario: When the authentication dialog box prompts the username and password of the domain administrator. I supply root as username and its corresponding password. Then I will prompt an error "The user name could not be found. But, I have noticed that when I supply a wrong password of root the it will prompt "Login failure: unknown user name or bad password. It seems that the windows machine was able to recognize the account somehow.
A time ago I've been trying to implement a PDC linux server with Samba and Openldap for centralized authentication for windows and linux clients, but I can NOT get it. So I read somewhere that there is another option called Directory Server and maybe that is possible to do. According to your experience do you recommend any 'how to' or 'tutorial' that will permit implement a PDC server for authenticating and sharing files and printers for windows and linux clients?
I maintain a samba PDC for a small business, our current setup does not work very well; on a hardware upgrade I directled imported the old ldap database and attempting to add machines to the domain causes all sorts of trouble.
I'm 95% sure the original database (which predates my employment) was created using the idealx smb-ldap tools, unfortunately on our current platform (debian lenny) these tools seem to be broken; the only things hey seem to do reliably are set passwords and add posix users, asking them to do anything involving samba/windows causes errors. The idealx tools seem to be abandoned, and I don't know enough perl to try and fix them.
Since the idealx scripts seem to be abandoned, and most of the good samba+ldap how-tos references the idealx tools, I was wondering what people use nowadays to manage there ldap directories; surely they aren't importing .ldif files to add new users/machines like I've been doing. Are people just writing thier own management scripts/web-apps? Or are the smb=ldap tools just broke on debian?how to generate the NT/LM password hashes and proper SIDs, does anybody have anything they could point me to about this?
First of all I am new user on fedora forum and I love Linux (special Redhat flavours) and want to replace windows into Linux Everywhere. I am having some issue in configuring PDC on Fedora,I want to replace my company Windows Domain controller and file server into fedora file and PDC, I tried from web and through 389-directory server but didn't succeed even once, how to configure PDC with Samba 4 + 389-directory Server, I have heard samba 4 is having awesome support and its better then windows DC, configuring Complete PDC. (Whatever need to configure PDC i.e. DNS, SAMBA 4, SWAT, WEBMIN, 389-Directory Server, Windows sync,).
I feel ashamed for even asking this, since it seems like there's about 3 samba questions here every day. However after an hour of searching, I keep finding strange variants that aren't what I need.
My Goal: Create a single file share on an Ubuntu Server - share it via samba to Windows clients that are on a domain with active directory. It sure would be nice if AD authentication would work - so users don't have to type in a linux user/passsword each time they want to access the share.
In my adventures, I've found the following items (which may overlap)
1. Joining the server to a Windows Domain
2. Turning the server into a Windows Domain Controller
3. Authentication with LDAP (still not quite sure how/what this would do)
4. Stuff with Kerberos
5. Lots of people bickering about Samba 3/4 & how it's impossible to make Samba a PDC.
I'm not sure if I need to make the ubuntu server a domain controller or not...all I want to do is create a file share and share it on the domain...I don't need to make the ubuntu server a domain controller for that, right? Maybe just a member? Maybe nothing at all?
I guess if I want to authenticate stuff correctly (or forward authentication requests? Not sure), I probably need to join the ubuntu server to the domain...I think.
But let's say I do join it to the domain...then how to I create a file share that is authenticated via active directory rather than a local ubuntu server account? I see a dozen guides on joining the server to the domain, but nobody ever mentions sharing the folder over the domain.
The lines are also blurred between joining Ubuntu to the domain and making it a domain controller. What should I keep an eye out to avoid in these tutorials?
I get lost between the Kerberos/LDAP/Samba/WinBind etc...and I have a feeling I don't need all of these for something this simple.
I have Ubuntu server 10.04 joined to a domain using Likewise Open. I can login using my domain credentials and have added my domain account to the sudoers file. Now that I've got it joined to the domain I want to add some samba shares and have domain members use their accounts to access them. However, no matter what combination of my domain name and the domain user or group I use in the valid users field it won't let me in. What's the proper way of inputting a domain user or group in the valid user field?
This is the entry I'm using for the share:
Code: [testshare] path = /srv/testshare valid users = @"Domain Name+Domain Group" (Have tried many things here) public = no writable = yes printable = no create mask = 0765
Intent is to use samba+winbind to authenticate Ubuntu desktop against a Windows 2008 R2 domain (seems like I was able to get it working temporarily but it stopped working after some time). Quick overview of the issue: winbind is failing to lookup group ID's for a domain user causing the domain user to receive group errors on login and an inability to use domain groups in other configuration (sudoers, etc)
- Very basic install, boot to Ubuntu Desktop 10.04 LTS 64bit install, basic install options, perform software updates
- Following an Ubuntu AD HowTo [URL]
- Install kerberos, samba, winbind packages
- Make changes to krb5.conf, smb.conf, files in pam.d/ (to make the home directory and restrict login based on group membership, which works even in the half-working state but requires SID instead of text name)
After a reboot I can login as a domain account but I get the following error(s):
groups: cannot find name for group ID #####
##### is usually a number that ranges from 10000 to 10020, based on the smb.conf line regarding idmap I will get multiple group errors (one for each group that the user belongs to that winbind can't lookup for whatever reason, some groups can be resolved - see below) If I log-out and then log-in as a local user I can run the following command: id username The output returns something similar to the following:
uid=10002(username) gid=10003(domain users) groups=10003(domain users),10033,10032,10031,10030,10029,10028,10027,1 0026,10025,10024,10023,10022,10021(some group),10020,10019,10018(some other group),10017,10016,10015,10014,10013,10012,10011(s ome other other group),10010,10009,10008,10007
On a working system (Ubuntu 10.10 and when 10.04 decides to work) each group is followed by parenthesis' and the name of the group, this result clearly shows that some groups can be looked up but for some reason other groups are failing An output of /var/log/samba/log.winbind produces the following entries (that are logged when you run the id command)
The above repeats for what looks to be each group that fails (based on count of entries)If I use wbinfo I can resolve text group name to SID and SID to GID
wbinfo -n groupname (returns proper SID) wbinfo -s SID (returns proper text group name) wbinfo -Y SID (returns proper linux mapped group ID)
Following that process for a group that my user belongs to that is not resolving (via the id username command) will return the group ID (GID) properly (even though id username fails to lookup info for that same GID) Version Information:
uname -a Linux hostname 2.6.32-33-generic #71-Ubuntu SMP Wed Jul 20 17:27:30 UTC 2011 x86_64 GNU/Linux lsb_release -a No LSB modules are available.
I am thinking about buying a domain name and hosting my web server.
I have seen pricing from $8 to $30 a year. Any favorites from fellow ubunters? Also this whole "whois" thing scares me, if I am correct my information I enter when buying the domain is enter into some big pool of information. People can find this information out and dig up important information. url Can I prevent this with private Whois or how do I set it up? This website examples some of my fears with this whole WhoIs thing, url whois/Private-Whois.html Does most/all domain registers come with email or just email forwarding or both? How does that work? At this moment, my only question about Web Hosting is how do I get Website Statistics as in: Stats, web analytics, web traffic stats and more? I will be web hosting through Ubuntu 9.10 gnome.
In the office there is a local network with samba+openldap PDC. The local domain name is company.net. The company desided to create a corporate Website on a remote hosting and desided that the site's domain should be company.net which is same as local network's domain name. So now it is not possible to reach that corporate website from within the company's local network because, as I guess, bind9 which is installed on above menioned PDC looks for company.net on a local webserver. Is there a possibility to let people from this local network browse the remote site?
I've been fighting with the Samba server for a while and I'm a bit frustrated at this point. When I try to add machines to my domain I get the "The username could not be found error" here is my smb.conf...
Code: [global] workgroup = INMANONE netbios name = PDC server string = Inman Domain Controller os level = 64 security = user passdb backend = tdbsam domain logons = yes domain master = yes local master = yes .....
Our system setup: windows server domain controller 2008 We are installed sambain Ubuntu 11.04, with ads authentication using winbind,i can able to give the access restriction from Linux for windows ADS User for linux samba share folderall are working fine from Linux,i want give the access fro domain user from MS -windows , what is the file permission owner ,etc, any one try this concept please give me a any document any example
I want to set a log off script for samba domain users. Actually I am facing a huge temp files related problem. So I want to set a batch file which will run when domain user log off. When user logout then batch file run and delete all temp files.I have already set batch file local group policy and it works for me, but I wants to set it from server side.
I'm configuring a classroom based on Linux (just Linux, without Windows) with user mobility. What I want is that any student will use its own 'username/password' on whatever computer getting its own data and without having to define every user on every computer. As far as Samba is very useful, even when I don't need Windows support I decided to base the solution on Samba. Right now I still have some problems and the solution doesn't work in my test environment. I defined a PDC (Samba 3.5 Domain Controller) on a Fedora 13 with 'homes', starting nmb and smb and it seems to work. On a Ubuntu 10.10 Workstation I built a Samba 'Domain Member Server' starting nmb, smb and winbind.
First question: should I define 'homes' on this server or not? I assumed 'not' as the 'homes' you have to use are the ones defined on the PDC, not on the DMS. Second question: does winbind run just on DMS? Not on the PDC too?
I defined the DMS 'machine' and some domain users on the PDC and I could 'join' the DMS to the PDC without any problem (join rpc ...) From the workstation I can use smbclient seeing a domain with two servers, one of which is the controller. I can connect to the home shares using the domain users which are authorized by the PDC. On the DMS I paid attention on nsswitch.conf and pam file running 'pam-auth-update'. So 'webinfo -u' provides a list of users on the domain, local users and domain users. The problem arrives when I try to connect from the session login screen on the workstation to 'mydomainmyuser'. PDC validates the user, if the password is right, and I get connected but not to my PDC homes.
Instead I get some errors starting with: 'could not update ICEAuthoriy file /home/mydomain/myuser/.ICEAuthority' It seems I'm in an empty space in an open but useless session which I can close later on.
Hereafter you will see the short smb.conf reported by testparm: PDC [global] workgroup = TESO-DOM server string = Samba Server Version %v interfaces = lo, wlan0 bind interfaces only = Yes .....
i have configured samba as file server in fedora 11,it works fine for both windows and linux machines .but i want to configure ldap and samba as domain controller. Googled a lot on internet every thing is confusing me .
