How to authorize a RaspberryPi device for 802.1x WLAN

The problem with RaspberryPi devices is, that they cannot authorize themselfs in 802.1x networks. With 'wpa_supplicant' authorizing on a 802.1x networks will be possible. Proceed as followed:

1. Change to '/etc/wpa_supplicant/'
2. Create the file 'wpa_supplicant.conf' and make following entries (in this case for the 'eth' SSID):

       network={
       ssid="eth"
       proto=RSN
       key_mgmt=WPA-EAP
       pairwise=CCMP
       auth_alg=OPEN
       eap=PEAP
       identity="NETHZ login"
       password="Netzwerk Passwort"
       phase1="peaplabel=auto peapver=0"
       phase2="auth=PAP"
       }
