in the community, we only support support the latest release. A lot has
changed since 1.9.3. 1.9.4-1.9.8 resolved a ton of tickets and there's
been a lot of features and refactoring since last April. You can get
commercial support from Red Hat for 1.9.x via the RH-SSO product.
RH-SSO 7.0 is based off of Keycloak 1.9.8.
As for your question, hopefully somebody else chimes in as I know
nothing about the spring security integration. What you may have not
configured in the Keycloak admin console page is the admin endpoint.
This is a proprietary endpoint that keycloak adapters expose to receive
back-channel logout events. If this URL is not set, then a backchannel
logout request is not sent to the application. I"m not sure if our
spring adapter supports backchannel logout.
Not much help, but its the most I can offer at the moment.
