I was expecting that since the encoding example in [1] inserts two \0
(NULL) characters before encoding, i.e.

printf '[email protected]\[email protected]\0passwod' | base64

I do not know if I am misreading the logs; maybe Aki can elaborate
some more, but I do know the encoding example lists the username
twice. And I am getting only it once when decoding the response I
found in the log file.
