[keycloak-user] Is a Keycloak server compatible with applications with older adapters ?

[Stian Thorgersen]

There's no explicit version check. For OpenID Connect there may be changes
to the token between versions that would cause issues for example. I'd say
1.6.1 adapter has a good chance to work with Keycloak 1.9 as I can't
remember anything we changed that would break it, but without going to
hundreds of JIRA issues and also testing it there's no way to be sure.

Due to the fast pace we've been having lately we've not been able to test
or document what adapters will work with what versions of the server. I
hope we can do this in the future.
