Cannot login to Trac with Konqueror or Opera

[killyourtv]

Konqueror 4.11.2
Debian Unstable

Trying to login to trac.i2p2.i2p yields the following:

The requested action is not supported by the KDE program which is implementing the http protocol.

Possible Causes:

This error is very much dependent on the KDE program. The additional information should give you more information than is available to the KDE input/output architecture.
Possible Solutions:

Attempt to find another way to accomplish the same outcome.

Login fails using https://trac.i2p2.de too. Same result with KHTML and Webkit.

Will investigate.

Also fails in ​Debian Wheezy.

Not sure yet if it's a KDE or Debian bug. I don't know if there's anything that 'we' can do to work around this.

After a bit of testing:

Browser	Status
Konqueror (in Debian and openSuse)	failed
Opera	failed
IE	success
Firefox	success
Chromium	success
Epiphany	success

After setting up Trac in a VM I found that Opera & Konqueror worked with tracd. Further experimentation in the VM lead to the discovery that disabling the setting AuthDigestDomain allowed both Opera and Konqueror to be able to login successfully. Also, none of the other browsers stopped working so I think this has been resolved.
