327c478bd9Sstevel@tonic-gate  * Determines the proper domain name for a realm.  This is mainly so that
337c478bd9Sstevel@tonic-gate  * a krb4 principal can be converted properly into a krb5 principal.
347c478bd9Sstevel@tonic-gate  * Currently, the same style of mapping file used in krb4.

367c478bd9Sstevel@tonic-gate  * If realm is NULL, this function will assume the default realm

387c478bd9Sstevel@tonic-gate  *
397c478bd9Sstevel@tonic-gate  * The returned domain is allocated, and must be freed by the caller.
