86 * KRBLOG is the log file for the kerberos master server. KRB_CONF is
87 * the configuration file where different host machines running master
88 * and slave servers can be found. KRB_MASTER is the name of the
89 * machine with the master database. The admin_server runs on this
90 * machine, and all changes to the db (as opposed to read-only
91 * requests, which can go to slaves) must go to it. KRB_HOST is the
92 * default machine * when looking for a kerberos slave server. Other
93 * possibilities are * in the KRB_CONF file. KRB_REALM is the name of
