I am still fiddling with Fedora Core 4. Yesterday I finally gave up on trying to pass authentication credentials from Fedora to the firewall and opened up anonymous access for http and https. It is a little of a defeatist attitude but I thought that Core 4 would be easier in this area and I needed to move on. The bottom line was that I needed yum to work. Yum was giving me somewhat misleading error messages about the repos and the base url when it actually was getting a html error 407. I tried a variety of supposed fixes. Ntlmaps looked the most promising but I could not get it to work.
Once I got Yum working I installed the Evolution connector for Exchange. It kind of worked. It cratered with a big old error message the first time I tried to use it but seemed to work anyway. I was able to read my email, look at contacts, and view the calendar. The error message bothers me. It is not ready for prime time in this state.
I also tried to change to a higher screen resolution. The gnome menus do not appear at the higher resolution on my mere mortal userid. It works with the root userid. Now that is a mystery.
