@paco We started to integrate DNS-UI (https://github.com/operasoftware/dns-ui) from @thomasp with #oauth2proxy and #keycloak.
We are also working on some features to bring it up to speed (see https://github.com/operasoftware/dns-ui/pull/218).

@paco @thomasp I stand corrected: it natively supports LDAP-based authentication but we do not use that feature.
