This function constructs the next KDC request for a TGS exchange, allowing the caller to control the transport of KDC requests and replies. On the first call, in should be set to an empty buffer; on subsequent calls, it should be set to the KDC’s reply to the previous request.
If more requests are needed, flags will be set to KRB5_TKT_CREDS_STEP_FLAG_CONTINUE and the next request will be placed in out . If no more requests are needed, flags will not contain KRB5_TKT_CREDS_STEP_FLAG_CONTINUE and out will be empty.
If this function returns KRB5KRB_ERR_RESPONSE_TOO_BIG , the caller should transmit the next request using TCP rather than UDP. If this function returns any other error, the TGS exchange has failed.
