/**
* @see http://tools.ietf.org/html/rfc1929
*
* Once the SOCKS V5 server has started, and the client has selected the
* Username/Password Authentication protocol, the Username/Password
* subnegotiation begins. This begins with the client producing a
* Username/Password request:
*
* +----+------+----------+------+----------+
* |VER | ULEN | UNAME | PLEN | PASSWD |
* +----+------+----------+------+----------+
* | 1 | 1 | 1 to 255 | 1 | 1 to 255 |
* +----+------+----------+------+----------+
*
* The VER field contains the current version of the subnegotiation,
* which is X'01'. The ULEN field contains the length of the UNAME field
* that follows. The UNAME field contains the username as known to the
* source operating system. The PLEN field contains the length of the
* PASSWD field that follows. The PASSWD field contains the password
* association with the given UNAME.
