24 * krb5_decode_kdc_rep() function.
30 Takes a KDC_REP message and decrypts encrypted part using etype and
31 *key, putting result in *rep.
32 dec_rep->client,ticket,session,last_req,server,caddrs
33 are all set to allocated storage which should be freed by the caller
34 when finished with the response.
36 If the response isn't a KDC_REP (tgs or as), it returns an error from
37 the decoding routines.
39 returns errors from encryption routines, system errors
