Comment 14 for bug 207723

I have the same problem here. But I think I know why this is happening, at least in my case.

Here is a part of the log produced by the Evolution:

** (evolution:19205): WARNING **: Invalid uri 'owaauth.dll'

(evolution:19205): libsoup-CRITICAL **: soup_message_set_request: assertion `SOUP_IS_MESSAGE (msg)' failed
e-data-server-ui-Message: Key file does not have key 'exchange:__qliu;<email address hidden>com_' in group 'Passwords-Exchange'

From this, I can see evolution got an invalid URI 'owaauth.dll'. Such URI is the used as the POST URI of a form-based authentication of OWA. Here is the HTML code from the OWA authentication page:

<form action="owaauth.dll" method="POST" name="logonForm" autocomplete="off">
<input type="hidden" name="destination" value="https://mail.company.com/exchange">
<input type="hidden" name="flags" value="0">
<input type="hidden" name="forcedownlevel" value="0">

Our company uses a customized HTML page as the form-based authentication page. Here, the action URI is a relative URI containing only "owaauth.dll". It is relative to "https://mail.company.com/exchweb/bin/auth/owalogon.asp?url=https://mail.company.com/exchange&reason=0&replaceCurrent=1". So the actual absolute URI should be "https://mail.company.com/exchweb/bin/auth/owaauth.dll". Firefox and Internet Explorer both have the correct behavior, while evolution-exchange connector thought "owaauth.dll" is an absolute URI (though in most cases, it is an absolute URI like "/exchweb/bin/auth/owaauth.dll").

The fix should be parsing the POST URIs per standard like Firefox and IE do.
