set yum on proxy - strange reaction
 

I have previously installed F10, under a proxy-isa. It was working. For various reasons, I reinstall from scratch F10. I use the same param, but there is impossible now to use yum for installing. Also the update package is not working (after installation of F10, if I try update, I receive the message that I am up-to day - can't believe!).
So, what are the inputs:
I add at the end of yum.conf the following:

proxy=http://wpad.xxx.local:8080
proxy_username=alfa\beta (alfa is a group)
proxy_password=password


the proxy is the same as in system/preferences/internet and network/network proxy.

Firefox is working OK.

at any try to give something as
yum install yumex
i receive the message

[root@aaaaaa]# yum install yumex
Loaded plugins: refresh-packagekit
Could not retrieve mirrorlist http://mirrors.fedoraproject.org/mir...a-10&arch=i386 error was

in yum.repos.de i have 4 files. fedora.repo contains the following:

It did not wprk. I was asked for a lot of other things to install. I think it is a local net problem, or... I don't know.
Thank you, anyway !

Is there any logging on the proxy server side? It would be nice if you could see 1) whether your request is reaching the proxy; 2) which username yum is really passing to the proxy server.
