OpenDSA FAQ
Login Failures
OpenDSA's score server uses an SSL certificate signed by Virginia Tech which your browser does not trust by default. You must manually add a security exception for the score server. To do so, simply surf to https://opendsa.cs.vt.edu where you should be prompted with a screen saying that the SSL certificate is untrusted and asking whether you would like to add a security exception. Follow the directions on the page to add the exception. Afterwards you should be able to login.
