##### Edit the Configuration Files

Modify the configuration files, `/etc/krb5.conf` and `/usr/local/var/krb5kdc/kdc.conf` to reflect the correct information (such as the hostnames and realm name) for your realm. MIT recommends that you keep `krb5.conf` in `/etc`.

Most of the tags in the configuration have default values that will work well for most sites. There are some tags in the `krb5.conf` file whose values must be specified, and this section will explain those as well as give an overview of all of the sections in both configuration files. For more information on changing defaults with the configuration files, see the Kerberos V5 System Administrator's Guide sections on configuration files.
