Need help in quickfix, python

Hi,

Grabbed this code from futures.io
I have no idea however how to make it send the Username tag on Logon.
Setting Message Type (A) Fields in FIX44.xml doesn't do a thing, 
so where it's at?

Output is
8=FIX.4.4
9=81
35=A
34=1
49=**.**
52=20161231-
04:02:16.063
56=cServer
98=0
108=30
141=Y
10=215

So it's lacking 553,554, and I think 57, how do one add them?

Thanks a million
