CAS PEM certificate location [Drupal 7]

To use the CAS PEM certificate installed on websites hosted on OIT webhosting, please use the following path:

 /etc/pki/tls/certs/ca-bundle.crt

Applying fix to resolve CAS redirect loop

1. Login to Plesk via https://hosting.gatech.edu
2. Click “Databases” in the side menu
3. Click “phpMyAdmin” to edit your database
4. Go to the “variable” table
5. Look for a variable named “cas_cert”
6. Click the “BLOB” link next to the variable name in the value column to download the “variable-value.bin” file
7. When you open the file in Notepad++ (or your text editor of choice), you’ll see a line similar to this:                                               s:33:" /etc/pki/tls/certs/ca-bundle.crt";
8. Delete the PEM path (DO NOT DELETE THE QUOTES!) and save the file
9. Click the “Edit” link next to the “cas_cert” variable
10. In the “value” row item, click the “Browse” button to upload the edited file
11. You can now login to your website (if you still see the CAS authentication error message, click the “reload” button on your browser)
