Barracuda SSO and DUO

Hey all. We are using Barracuda SSO on laptops so they connect to the VPN when they login (at the login screen). We also wanted DUO to work at the login screen as well, but I can only get one or the other to work. I know there is a credential whitelist but I can’t find any Barracuda guid to whitelist. Any ideas?

Credential provider whitelisting with Duo WinLogon means that you can use either the third-party credential provider, or Duo’s. It will not add Duo Auth to the third-party credential provider login. This is explained in more detail at
