[keycloak-user] Using Keycloak 3.4 with Spring Boot 2 Adapter 4

[Benke, Tim]

Hello everybody,

It’s intuitively clear to me that an outdated adapter communicating with a *newer* Keycloak isn’t a great idea and the documentation suggests importing the javascript adapter from the server itself.

What about the opposite case of a new backend adapter with version 4.0.0.Final and an older Keycloak 3.4.3. Is this insecure? We’re considering this option to reduce the hassle of updating keycloak itself and upgrading our custom theme.

Best regards,
