We just developed a WebApp in Dataiku, and are trying to make it public, to set it as an applicative frontend.
Here, the documentation mentions that to do so, we should go to 'Administration > Settings > Login & Security, and add the “PROJECTKEY.webappId” in the authentication whitelist'. However, we cannot find the 'Authentication whitelist' option. Here is how the 'Administration > Settings > Login & Security' screen looks on our end:
Public webapps is a new feature of DSS 8.0 (https://doc.dataiku.com/dss/latest/release_notes/8.0.html#public-webapps-and-impersonation-in-webapp...)
You thus need to upgrade to DSS 8.0 in order to benefit from this feature. Please note that since this is a brand new release, we'd recommend that you look into upgrading non-production instances first.
