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