- * Given a Kerberos realm, find a host on which the Kerberos database
- * administration server can be found.
- *
- * krb_get_admhst takes a pointer to be filled in, a pointer to the name
- * of the realm for which a server is desired, and an integer n, and
- * returns (in h) the nth administrative host entry from the configuration
- * file (KRB_CONF, defined in "krb.h") associated with the specified realm.
- *
- * On error, get_admhst returns KFAILURE. If all goes well, the routine
- * returns KSUCCESS.
- *
- * For the format of the KRB_CONF file, see comments describing the routine
- * krb_get_krbhst().
- *
- * This is a temporary hack to allow us to find the nearest system running
- * a Kerberos admin server. In the long run, this functionality will be
- * provided by a nameserver.
