<br>
I just checked out the <a href="https://cacert.at/homepw">https://cacert.at/homepw</a>
URL you mentioned. The reason the <a href="http://nerdbank.org/rp">http://nerdbank.org/rp</a>
site rejects that URL is because the HTTPS certificate is not signed by a
recognized cert authority at the server hosting the site. <br>
<br>
This doesn't actually have anything to do with the AOL issue right? (does this
deserve its own thread?) I just want to make sure I'm understanding the issue
you're getting at. I'm also not familiar with this CX thing. Is
that a certificate exchange protocol that's in the works?<br>
<br>
Thanks.<br clear=all>

To: <a href="mailto:dotnetopenid@googlegroups.com" target="_blank">dotnetopenid@googlegroups.com</a><br>
<br>
<br>
Thanks for reporting this, Joel. This is a bug in AOL's encoding/decoding
of the return_to URL, as I detail below. I'll forward this onto the AOL
OpenID folks (as soon as I can figure out who they are) and suggest they fix
this bug prompto!<br>
<br>
As can be seen in the below log, DotNetOpenId is sending AOL a return_to URL
with a twice-URL-encoded + sign as the value for the token parameter, as
appropriate. That is, the plus sign is an actual character in the (base
64 encoded) value, which must be URL encoded because it is a URL
parameter. Then since the return_to URI is itself a URL parameter, it is
encoded again. <br>
<br>
But when the auth message comes back from AOL (and only AOL has this issue,
reportedly starting 12/31/08) the + sign character in the return_to URL has
been decoded by AOL rather than being preserved as DotNetOpenId had written
it. As a result, the + sign is misinterpreted as a URL encoding of the
space character, causing the base64 decoding operation to fail.<br>
<br>
<b>Analysis: AOL is decoding the return_to parameter, and not properly
re-encoding it before sending it back to the RP.</b><o:p></o:p></p>
