I'm doing some experiments with Samba and Kerberos on Ubuntu Server Cuttlefish, by installing samba, krb5-config, and winbind. When installing Kerberos in interactive mode, it asked some questions to automatically config some settings:
+------------------+ Configuring Kerberos Authentication +------------------+
| When users attempt to use Kerberos and specify a principal or user name |
| without specifying what administrative Kerberos realm that principal |
| belongs to, the system appends the default realm. The default realm may |
| also be used as the realm of a Kerberos service running on the local |
| machine. Often, the default realm is the uppercase version of the local |
| DNS domain. |
| |
| Default Kerberos version 5 realm: |
| |
| MYDOMAIN.COM________________________________________________________________ |
| |
| <Ok> |
| |
+---------------------------------------------------------------------------+
# specify the hostname
+------------------+ Configuring Kerberos Authentication +------------------+
| Enter the hostnames of Kerberos servers in the SRV.WORLD Kerberos |
| realm separated by spaces. |
| |
| Kerberos servers for your realm: |
| |
| dc1.mydomain.com____________________________________________________________ |
| |
| <Ok> |
| |
+---------------------------------------------------------------------------+
# specify the hostname
+------------------+ Configuring Kerberos Authentication +------------------+
| Enter the hostname of the administrative (password changing) server for |
| the SRV.WORLD Kerberos realm. |
| |
| Administrative server for your Kerberos realm: |
| |
| dc1.mydomain.com____________________________________________________________ |
| |
| <Ok> |
| |
+---------------------------------------------------------------------------+
After messing things up, how do I properly clean the mess on the server to start fresh with a new domain? And most importantly, how to start the Kerberos configuration wizard again?
