likewise-open and samba as pdc

  • 772

We have successfully implemented a Samba Primary Domain Controller for a hybrid Windows-Linux environment. So now I am setting up dual-boot clients with Windows XP and Ubuntu 9.10.

Windows XP can be easily added to the Samba Domain. Everything is manageable. No worries. But when I try using likewise-open 4.1 to add the Ubuntu 9.10 to the samba domain, it cannot locate the domain controller. 

domainjoin-cli --loglevel verbose join MYDOMAIN root

Error: Unable to resolve DC name [code 0x00080026]

Resolving 'MYDOMAIN' failed. Check that the domain name is correctly entered. Also check that your DNS server is reachable, and that your system is configured to use DNS in nsswitch.

I even tried mydomain.com variations but to no avail. What am I missing ?

I read up a document on MSDN wherein it says that the Domain Controller creates some SRV records in the DNS server. I guess, I don't have them on my BIND. Do you think that is the problem ? If yes, can anyone please point out how and what SRV records need to be added.

Thanks.

    If you have Samba as a PDC, you don't need likewise. Just install samba and follow the instructions to join the samba domain at http://www.samba.org/samba/docs/man/Samba-HOWTO-Collection/FastStart.html#id2555963

    Likewise assumes an Active Directory Domain Controller. If you want a Samba to have those functionalities, you need to go for Samba4 (not yet recommended for production). The errors you're getting is because you don't have DNS and Kerberos configured has expected in a domain controller (for example, try resolving _tcp.<DOMAIN>).

  2. Is your domain controller listed in /etc/resolv.conf in the Ubuntu hosts you're trying to join to the domain?

    What happens when you try

    ping mydomain.com

    or 

    nslookup mydomain.com

    from the Ubuntu hosts?

    Update: There are some suggestions for the error you're getting in a post and comments here. However, the current version of Likewise is 5.3, which is a bit ahead of the one you're using from the Ubuntu Karmic repository. If none of the steps mentioned in the link above resolve the issue, the next step I would take would be to download the current version of Likewise for Ubuntu/Debian here and the quick start guide here (pdf), upgrade, and see if this is fixed in the latest version.

    There is also an implementation guide to using Likewise with Samba here (pdf).
