    | AUTH TYPE | LEN | USERNAME | LEN | PASSWORD |
    +-----------+-----+----------+-----+----------+
    |     1     |  1  | 1 to 255 |  1  | 1 to 255 |
    +-----------+-----+----------+-----+----------+

  Where:

    o  AUTH TYPE
	   o  0x00 NO AUTHENTICATION REQUIRED
       o  0x01 USERNAME/PASSWORD
    o  LEN       length of the USERNAME
    o  USERNAME  username
    o  LEN       length of the PASSWORD
    o  PASSWORD  password
```
