Description Fredrik Sundberg

Build Identifier: 20100917-0705

We are running a Hudson instance behind IBM WebSeal (that gives us single sign on functionality), and I cannot get the server setup to work 

I have added server, label, user & password, but the error message is (most often):

!ENTRY org.eclipse.mylyn.builds.ui 4 0 2011-02-17 08:42:21.493

Sometimes i get this exception instead:

Do you know what type of proxy authentication IBM WebSeal uses?

(In reply to comment #1)
> Do you know what type of proxy authentication IBM WebSeal uses?

NTLM in our case i believe. Do you want me to run with some debugging on (if that is possible)?

Comment 3 Steffen Pingel

Mylyn has limited support for NTLM authentication which is described here: http://wiki.eclipse.org/index.php/Mylyn_FAQ#NTLM_authentication . At this point supporting single-sign on systems does not fall into the core scope of the project and due to time constraints we are unable to resolve this request at the moment. The bug has been marked helpwanted though to indicate that we would be happy to support a community contribution to resolve it.

Ok thanks, by the way HttpClient 4.1 is released with NTLM support.

Yes, we are planning to move to the new HttpClient release: bug 335254.

Mylyn has been restructured, and our issue tracking has moved to GitHub [1].

We are closing ~14K Bugzilla issues to give the new team a fresh start. If you feel that this issue is still relevant, please create a new one on GitHub.
