The krb5.conf file contains Kerberos configuration information, including the locations of KDCs and admin servers for the Kerberos realms of interest, defaults for the current realm and for Kerberos applications, and mappings of hostnames onto Kerberos realms. You should install your krb5.conf file in the /etc directory. You can override the default location by setting the environment variable KRB5_CONFIG. While managing Novell Kerberos KDC, when you do not specify any of the mandatory parameters, the values are taken from the /etc/krb5.conf file.
For a sample configuration file, refer to Section A.0, Sample krb5.conf File.
