Comment 1 Donny Kavanagh 2005-09-08 17:12:57 EDT
Because i needed to get this system updated asap, i googled and found this

i set it up to do NTLM -> Basic proxy translation, so to urlgrabber/yum it the
proxy server appeared to be a no authentication proxy (rather then ntlm) and it

So it would seem NTLM within urlgrabber is either broken, or not supported. 
That proxy/translator tool is however written in python.

This report targets the FC3 or FC4 products, which have now been EOL'd.

Could you please check that it still applies to a current Fedora release, and
either update the target product or close it ?

Wow, umm... i submitted this bug 1.25 years ago.

I no longer run Fedora Core, i use mainly centos now, but i will try to see if i
can quickly setup a box of the latest release.  If it takes another year to
address my update however, i have a feeling we aren't going to get anywhere.

Fedora Core 4 is no longer maintained.

Setting status to "INSUFFICIENT_DATA". If you can reproduce this bug in the
current Fedora release, please reopen this bug and assign it to the
corresponding Fedora version.
