Updating the Kerberos keytab file

If you update BDD's current keytab file or create a new one, you can use the bdd-admin script to publish the new or updated file to the rest of the cluster.

When you run the script, you must provide it with the absolute path to the new or modified file. The script renames the specified file to bdd.keytab (if necessary) and copies it to $BDD_HOME/common/kerberos on all nodes.

For more information on updating your Kerberos configuration with the bdd-admin script, see kerberos.

To update the keytab file:

  1. On the Admin Server, edit the current BDD keytab file or create a new one.

    The current file is named bdd.keytab and located in $BDD_HOME/common/kerberos.

  2. Go to $BDD_HOME/BDD_manager/bin and run: 
    ./bdd-admin.sh publish-config kerberos -t <file>
    Where <path> is the absolute path to the new or modified keytab file.
  3. Restart your cluster so the changes take effect: 
    ./bdd-admin.sh restart [-t <minutes>]
