Why OpenConnect no longer works with TRIUMF VPN

Authentication for TRIUMF VPN is based on TRIDENT which redirects to for the password entry, and  subsequent multi-factor authentication.   Therefore, the VPN client must handle the web-page redirect, and receive the token generated by the authentication procedure.   At present, the only client capable of interacting with the Ivanti Secure VPN-server in this way is the Ivanti Secure VPN-client provided by the vendor.

Ivanti Secure Issues

After a certain amount of logins (usually 30+ logins) to TRIUMF VPN with the Pulse Secure Linux client, you may no longer be able to successfully make a connection, even though things seem otherwise fine with the Pulse Secure client. You may need to delete the Pulse Secure client cookies due to a bug in the software before you can connect to the VPN again. In order to clean out your cookies, make sure you're disconnected from VPN and run the following commands in a terminal:

rm -f ~/.pulsesecure/cef/Cookies

rm -f ~/.pulsesecure/cef/Cookies-journal

Once you've completed these commands, your cookies files should be removed and you can try logging in again.
