* machine with the master database. The admin_server runs on this
* machine, and all changes to the db (as opposed to read-only
* requests, which can go to slaves) must go to it. KRB_HOST is the
* default machine * when looking for a kerberos slave server. Other
* possibilities are * in the KRB_CONF file. KRB_REALM is the name of
* the realm.
