There are several ways to configure a KDC. The simplest ways use the kdcmgr utility to configure the KDC automatically or interactively. The automatic version requires that you use command-line options to define the configuration parameters. This method is especially useful for scripts. The interactive version prompts you for all information that is needed. For pointers to the instructions for using this command, see Configuring KDC Servers.
You can also use LDAP to manage the database files for Kerberos. For instructions, see How to Configure the Master KDC to Use an LDAP Directory Server. LDAP simplifies administration at sites that require coordination between the Kerberos databases and their existing directory server setup.
