Native Redmine / ChiliProject OpenID authentication does not work, for example, with Google. And I doubt it does with other OpenID providers... The OpenID Fix plugin for Redmine and ChiliProject fixes this issue and lets users use their third-party OpenID logins to access Redmine/ChiliProject.
Additionally, this plugin implements OpenID providers whitelisting, thus letting administrators control, which providers can be used to sign in.
