[GNC] AqBanking help for Citi CC

[Jim Maki]

I just successfully set up GnuCash to download Citi credit card data 
using AqBanking - for now all you have to do is add a space to the end 
of your userid (assuming everything else is correct).The issue seems to 
be with Citi ...

When it consistently failed with code 403, I turned on OFX logging 
(export AQOFX_LOG_COMM=1), snagged the OFX request (from /tmp/ofx.log), 
formatted it to make it more readable, and created a bash script using 
curl to make the OFX request. Paradoxically it worked while the 
equivalent un-beautified GnuCash request failed.

After little debugging, the key lines in the GnuCash ofx.log were:

================== OFX ==================
...
... <USERID>myuserid
<USERPASS>mypassword
...
================== OFX ==================

The above will work if you add a space either at the end of the 
"...<USERID>myuserid" line, or before "<USERPASS>" in the next line. At 
the GnuCash user interface level that involves adding a trailing space 
to the AqBanking userid for Citi.

For reference, below is the OFX template file I use to feed my 
curl-based script. Eventually GnuCash makes an equivalent request. 
(Again, eliminate the leading spaces before "<USERPASS>" and it, too fails.)

If GnuCash did prettified SGML it would avoid this problem with Citi's 
parsing.
