34 * Determines the proper domain name for a realm.  This is mainly so that
35 * a krb4 principal can be converted properly into a krb5 principal.
36 * Currently, the same style of mapping file used in krb4.
37 *
38 * If realm is NULL, this function will assume the default realm
39 * of the local host.
40 *
41 * The returned domain is allocated, and must be freed by the caller.
42 *
43 * This was hacked together from krb5_get_host_realm().
