### kdc.conf

The `kdc.conf` file contains KDC configuration information, including defaults used when issuing Kerberos tickets. Normally, you should install your `kdc.conf` file in the directory `/usr/local/var/krb5kdc`. You can override the default location by setting the environment variable `KRB5_KDC_PROFILE`.

The `kdc.conf` file is set up in the same format as the `krb5.conf` file. (See krb5.conf.) The `kdc.conf` file may contain any or all of the following three sections:

kdcdefaults
  Contains default values for overall behavior of the KDC.
realms
  Contains subsections keyed by Kerberos realm names. Each subsection describes realm-specific information, including where to find the Kerberos servers for that realm.
logging
  Contains relations which determine how Kerberos programs are to perform logging.
