encryption problem with university network

[Guest]

Hello,
I've got an "Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)" network card,
lsmod tells me the module iwl3945 is loaded and I am able to connect to the unencrypted guest-network.

I need to connect to a network with the following settings:

http://www.snt.utwente.nl/handleidingen/1/118

I've seen it working with ubuntu 10.10 with that configuration.

I filled all these settings into the network-manager configuration via the plasma-widget and it does not connect (without telling me why)
wicd also doesn't connect, telling me "authentication failed".

Any ideas?
How can i get specific connection errors?

Thanks in advance.

Re: encryption problem with university network

"Authentication failed" is a specific connection error

The network uses certificate-based authentication in addition to username and password. Do you have the proper certificate installed?

ls /etc/ssl/certs/ | grep GTE

[b]GTE_CyberTrust_Global_Root.pem[/b]
GTE_CyberTrust_Root_CA.pem

The certificate is installed by default.

I've checked username and password more than twice... I can copy them out of the configscreen and log into some web-applications.

Edit:
Ok i got it working... by using gnome's network manager.
I installed network-manager-gnome and configured it by running nm-connection-editor... now i'm connected.
Only the applet is not working:

nm-applet
** Message: applet now removed from the notification area
** (nm-applet:5285): DEBUG: old state indicates that this was not a disconnect 0
** (nm-applet:5285): DEBUG: old state indicates that this was not a disconnect 0

** (nm-applet:5285): WARNING **: Fallback icon 'gtk-dialog-error' missing: (0) Icon 'gtk-dialog-error' not present in theme
**
ERROR:applet.c:2932:nma_icons_reload: assertion failed: (applet->fallback_icon)

Would be great to get it working, until kde's tools do the job... what's wrong with my notification area?
