How to connect to the university's network using certificate

I'm trying to connect to the universities network which requires a certificate and authintication. I used to be able to connect using wpa_supplicant, but I'm not sure how it should be set up with wicd.
For wpa_supplicant, they give the following instructions:
"""
Create a file
/etc/wpa_supplicant/wpa_supplicant.conf

Type the following parameters:
ctrl_interface=/var/run/wpa_supplicant
network={
�� scan_ssid=1
�� ssid="HUJI-netX"
�� key_mgmt=WPA-EAP
�� eap=PEAP
�� identity="XXXXXX%<email address hidden>"
�� password="XXXXXX"
�� ca_cert="$CERT.pem"
�� phase1="peaplabel=0"
�� phase2="auth=MSCHAPV2"
}

Note:
- In ca_cert you need to replace the $CERT with the location of your certificate
(To find the location type the command:
locate *.pem|grep AddTrust (or AddTrust_External)
Note that in Ubuntu the command is locate *.pem|grep /etc/ssl/certs/AddTrust or AddTrust_External)
