This document (7000207) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server 10 SP1

Situation

When joining an Active Directory domain using theYaST2 module 'WindowsDomainMembership'the following error is experienced:

ERROR: Failed to join domain: No logon servers found

Looking at the log file /var/log/YaST2/y2log the error is similar to the following

'exit' => 255,
'stdout' => ''
};

Resolution

Please update Samba to version 3.0.32 or later.
  1. Ensure the serviceswinbind, nmbandsmbare not active / running:
    rcwinbind stop ; rcnmb stop ; rcsmb stop

  2. Use the YaST2 module 'Kerberos Client' to configure the domain settings

  3. Edit as user root the file/etc/samba/smb.conf and set the following options in the global section

    workgroup = DOMAINNAME
    password server = IP_OF_PASSWORD_SERVER
    realm = KERBEROS_REALM
    security = ads

    Save the changes and close the file.

  4. Run as root the command

    net ads join -U Administrator@DOMAIN

    Enter the Administrator password when being asked.

  5. Once the command completed successfully start the services winbind, nmb and smb using

    rcwinbind start ; rcnmb start ; rcsmb start

  6. Check using smbclient if authentication against the password server works:

    smbclient -L SMB-SERVER -U USERNAME

    If authentication works properly all available shares of SMB-SERVER will be displayed

Additional Information

Root cause

When called the YaST2 Windows Domain Membership module writes a temporary smb.conf and krb5.conf which are being used to connect to the domain. However, since the password server is not included in the temporary configuration a join is not possible.
