Description Nicolas Mailhot 2012-02-19 08:00:50 UTC
http://code.google.com/p/chromium/issues/detail?id=7338 and

there is no clean way for a proxy or captive portal to get a web client to
display an authentication dialog when user credentials expire while he is
browsing on an https url.

(to be sure, the previous methods were insecure and hackish but they existed
because nothing better was available)

The IETF finally set up to fix this problem and defined a standard HTTP error
that lets access control equipments tell the web client authentication or
re-authentication is needed and where the authentication form is located.


→ <http://www.rfc-editor.org/queue2.html#draft-nottingham-http-new-status> (the
spec is approved and in the queue for publication as RFC)

Please add error 511 handling in libreoffice (for example, when trying to download/update extensions)

It shouldn't be more complex than launching the URL indicated in the error 511 in the default used browser

Dear Nicolas Mailhot,

To make sure we're focusing on the bugs that affect our users today, LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed bugs which have not been touched for over a year.

There have been thousands of bug fixes and commits since anyone checked on this bug report. During that time, it's possible that the bug has been fixed, or the details of the problem have changed. We'd really appreciate your help in getting confirmation that the bug is still present.

If you have time, please do the following:

Test to see if the bug is still present with the latest version of LibreOffice from https://www.libreoffice.org/download/

If the bug is present, please leave a comment that includes the information from Help - About LibreOffice.
If the bug is NOT present, please set the bug's Status field to RESOLVED-WORKSFORME and leave a comment that includes the information from Help - About LibreOffice.

Please DO NOT

Update the version field
Reply via email (please reply directly on the bug tracker)
Set the bug's Status field to RESOLVED - FIXED (this status has a particular meaning that is not 
appropriate in this case)

If you want to do more to help you can test to see if your issue is a REGRESSION. To do so:
1. Download and install oldest version of LibreOffice (usually 3.3 unless your bug pertains to a feature added after 3.3) from http://downloadarchive.documentfoundation.org/libreoffice/old/

2. Test your bug
3. Leave a comment with your results.
4a. If the bug was present with 3.3 - set version to 'inherited from OOo';
4b. If the bug was not present in 3.3 - add 'regression' to keyword
