Connecting UMD-Secure wireless (University of Maryland, College Park) was such a hard task because the University IT Support does not have clear instructions.
After a hunt online, this is what I found: You need the following settings before you can access UMD-Secure.
Security: WPA & WPA2 Enterprise
Authentication: Tunneled TLS
Anonymous identity: anonymous
CA certificate: [select /etc/ssl/certs/Thawte_Premium_Server_CA.pem
Inner authentication: PAP
Username: UID username
Password: UID password
Save the dialog box and close it. Now select UMD-Secure to connect. Bingo!
