CentOS 5 Server :: Samba PDC+LDAP, Failed To Join Domain For Win2k8?
Dec 8, 2009
I've setup my samba pdc with ldap, and I can see my shared files (public), which i think is an indication that my samba is working. But I can't seems to get my win2k8 machine to join my domain.
My domain admin is : root system admin: root password for both domain admin and system admin are the same The message that I get from Win2k8 when I try to join a domain is "The specified computer account could not be found. Contact an administrator to verify the account is in the domain. If the account has been deleted unjoin, reboot, and rejoin the domain"
I would like to join SLES server to Microsoft Server 2008 Active Directory to enable domain authentication when accessing samba shares. When I run
Code:
net ads join -U administrator
I get the following error
Code:
"Failed to join domain: Improperly formed account name."
I tried the same samba configuration on another server (OpenSuse 11.2) without any problem, so I think it is somehow connected with the Samba version, but I'm not sure. Has anybody experienced this behaviour?
Code:
kinit administrator@MYDOMAIN
the package versions on SLES 10 SP2 (x86_64) are following
I am running Red Hat Enterprise Server 6.0 I am having issues getting kerberos configured as a client to join a domain. Im getting below error message. "Failed to join domain: failed to connect to AD: KDC has no support for encryption type"
I have a centos 5 server joined to a win2003 active directory domain. It's a virtual machine, so i had to sync the date (ntpdate) because it was 12 minutes different. It worked, but not ntlm authentication is not working anymore. If i rejoin the domain i get:
net ads join -U administrator@MYDOMAIN.COM administrator@MYDOMAIN.COM's password: Failed to set password for machine account (NT_STATUS_DISK_FULL) Failed to join domain: NT_STATUS_DISK_FULL
Good evening, I get the following error when prompted for my user name and password credentials that have access to the domain rights on the server. After typing in root and the password I get the following.
"The specified computer account could not be found. Contact an administrator to verify the account is in the domain. If the account has been deleted, unjoin, reboot and rejoin the domain."
Posted below is my smb.conf file, however I feel like I am screwing up the last steps with group-mapping, net commands, and creating accounts.

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 installed Fedora 11 and all updates. Samba 3.4.1. When join to domain from WinXP box with sp3 show error. The specified network password is not correct.
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.
We've been running samba on linux for a while and everything was fine. All of a sudden when you add new clients to the domain you get the error message :Logon Failure:unknown user name or bad password. This to me seems like a windows error message and not a samba error. When you remove an existing machine (ie on domain) and then try to rejoin it to the domain you fail.
I just tried to build my own samba/ldap server on opensuse 11.3 and i am continuously getting an invalid credentials error when doing the smbpasswd -a command. Below are my smb and ldap files.

Regarding domain names for LDAP root, you should use something like dc = domain, dc = country eg ar, cl, is br. or better use some other domain?That is, suppose the root domain is dominio.es Is it advisable to do so? I ask because I have seen many implementations (especially Microsoft AD), which states rather dominio.local or dominio.int.
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.
Im currently using an english book to setup my samba server, and im having problems understanding it.
I dont want to use root to join clients to the domain; i prefer creating a plain user.
Ok, so, the steps i follow are:
net groupmap add unixgroup=srvadmins ntgroup="Server Admins" net groupmap add ntgroup="Domain Admins" unixgroup=dmnadmins rid=512 type=d net rpc rights grant 'ORAServer Admins' seMachineAccountPrivilege
This way, i have a group called srvadmins with permissions to join clients, a group called dmnadmins with permissions to manage users and other permissions, and root.
Now, users: "root", "dmnadmin"(from dmnadmins group) and "srvadmin" (from srvadmins group) can add machines to domain. Root because is root, srvadmin because i granted permissions, and dmnadmin because is admin
So i wonder, why srvadmins group is needed to be granted privileges?
I tryed to lower dmnadmins privileges by revoking semachineaccountprivilege privilege, but didnt worked
net rpc rights revoke 'ORADomain Admins' seMachineAccountPrivilege
looks like its privileges comes from another group and it user managed to add a machine to the domain correctly.
Ok, so, is this really usefull? why do i need 3 kind of users to be able to join to the domain?
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 would like to setup LDAP (openldap) with Samba. I would like to know what should I setup first? Should I setup LDAP before Samba or Samba before LDAP?
I've been testing a PDC with samba and LDAP these days with the following unsolved issue. 1. I can add the client PC (Windows XP SP3) with the Domain Admin user (Manager) from the client PC, but when i try to add a user I get this message "The trust relationship between this workstation and primary domain failed", so as it can be added later I ignored this message and choose 'close' and reboot the PC. 2. Since the login screen is showed, the message 'Duplicate name exists on the network' appears. So I try to log on with a valid domain username and password after pressing ctrl+alt+del and get the error message: "System cannot log you on because domain rmprb is not available"

I installed CentOS 5.2 and then run yum update. I configured this server as LDAP/Samba primary domain controller. LDAP seems to be OK and for testing I am able to create users with:smbldap-tools useradd -am usernameI can ssh into the server as root and also as a Linux user which was locally created in the server. But ssh into the server as LDAP user fails (from a Fedora 11 machine) with "Permission denied, please try again", prompting again for password.Some data:
I have too many problems to join my OpenSuSE 11.2 with Samba 3.5.4 in a Windows 2008 Active directory Forest (MYDOMAIN.LOCAL). I have updated Samba to 3.5.4 after read that default 11.2 version have too many bugs. Now, when I try to join the Domain MYDOMAIN.LOCAL via yast i have only an undebuggable error "unknown error". For yast, my Suse is joined but i'm unable to authenticate, i can't see "MYDOMAIN.LOCAL" at KDM login and if i try to lookup forest i have this error:
Code: wbinfo -u Error looking up domain users but i'm able to retrive ticket via kinit Code: # kinit Administrator Password for Administrator@MYDOMAIN.LOCAL:

have you a samba version tested against Active Directory 2008? can you link me the repository or help me to solve this?
I was wondering if there is any way to enable an MS Windows client that is otherwise unable of joining a domain to join a domain controlled by (open)SUSE? Is that inability only for joining a Windows based domain but a client that runs XP Home Edition or similar domain- incapable version of Windows could join a domain if it was controlled by Linux?Pardon my newbie style, but answer doesn't have to be detailed step-by-step, just yes/no answer with some pointers would do. I am not new to linux but new to network services... search engines weren't friendly when asked this question at the search bar...
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?
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 try to setup a client (for password /etc/passwd) to my samba server, without using the kerberos. let's make it simple: just samba. here are the errors: I have installed winbind, portmap, and samba/smbclient packages on the workstation linux ubuntu , which is intended to be client to samba for /etc/password attached to the server. At boot nothing changed, and the /etc/password is not attached to samba. So my passwords are stil the local of hte client, and not the server. This is my config of the client workstation:
I am facing a problem which joining my linux machine to SAMBA Primary Domain Controller (Running on Centos 5). I am able to join Windows XP machine to the domain, but i have no idea how to do it on Linux Client.
A very strange thing happened to me today after upgrading a Lenny server to Squeeze. All seems to be working great except for the fact that I cannot join the server to our domain (made a work copy of the virtual machine holding Debian, upgraded that, renamed and changed IP).
The problem I'm having is related to Samba as far as I can tell. On the Lenny server(s) I have the 'net' command to join a server to a domain but not on the upgraded version (Squeeze). It just says command not found and there's indeed no 'net' in /usr/bin where it's supposed to be.
I imagine that something went wrong upgrading Samba although the rest works, the daemons are running, kerberos works (kinit, klist), and so on, I only miss the net command.
Is there a way to install that separately or which package do I have to reinstall (samba-common, sambafs, ...)?
I have other servers (clean install and upgrade from Lenny to Squeeze) that do have the command in /usr/bin. Can I just copy it over from one to another or do I have to remove and reinstall Samba all together?
