public abstract class KdcReq
extends KerberosMessage

The KDC-REQ data structure. It will store the object described by the ASN.1 grammar :

 KDC-REQ    ::= SEQUENCE {
      -- NOTE: first tag is [1], not [0]
      pvno            [1] INTEGER (5) ,
      msg-type        [2] INTEGER (10 -- AS -- | 12 -- TGS --),
      padata          [3] SEQUENCE OF  OPTIONAL
                            -- NOTE: not empty --,
      req-body        [4] 
 }
