347c478bdstevel@tonic-gate * Determines the proper domain name for a realm.  This is mainly so that
357c478bdstevel@tonic-gate * a krb4 principal can be converted properly into a krb5 principal.
367c478bdstevel@tonic-gate * Currently, the same style of mapping file used in krb4.
377c478bdstevel@tonic-gate *
387c478bdstevel@tonic-gate * If realm is NULL, this function will assume the default realm
397c478bdstevel@tonic-gate * of the local host.
407c478bdstevel@tonic-gate *
417c478bdstevel@tonic-gate * The returned domain is allocated, and must be freed by the caller.
427c478bdstevel@tonic-gate *
437c478bdstevel@tonic-gate * This was hacked together from krb5_get_host_realm().
