Ideally, the Mojolicious::Plugin::OAuth2 library should deal with this implicitly, probably making use of JWT. But as of now, this is the best way to implement it. To test: 1. Have a working SSO solution (ktd --sso) 2. Click to login using SSO => SUCCESS: Notice a 'state' parameter on the URL, looks like a random thing 3. When you login, no error is reported -- You are receiving this mail because: You are watching all bug changes.
