[keycloak-user] Fwd: Help

Hello, I am trying to integrate keycloak in my system. I already have two authentication applications that i cant change/update its code. I would like to have a single login page for all my applications using keycloak and let keycloak communicate with them authenticate/authorize only once (single sign on) regardless of whether the user enters the first application credentials or the second one. I first saw the broker identity provider feature you have and i configure it but it still didnt work fine. (i probably missed some configuration) or maybe i need to add custom code in my aplication. Second i saw the SPI and thought of writing a customized authentication jar to change in keycloak authentication to communicate with my authentication applications. I saw in git hub we have ubder example/provider/authenticator a sample code. I tried to import it in my IDE but im facing this issue: Failed to execute goal on project authenticator-required-action-example: Could not resolve dependencies for project org.keycloak:authenticator- required-action-example:jar:4.3.0.Final-SNAPSHOT: The following artifacts could not be resolved: org.keycloak:keycloak-core:jar:4.3.0.Final-SNAPSHOT, org.keycloak:keycloak-server-spi:jar:4.3.0.Final-SNAPSHOT, org.keycloak:keycloak-server-spi-private:jar:4.3.0.Final-SNAPSHOT, org.keycloak:keycloak-services:jar:4.3.0.Final-SNAPSHOT: Could not find artifact org.keycloak:keycloak-core:jar:4.3.0.Final-SNAPSHOT -> [Help 1] [ERROR] Can you guide on whether this version is used or not on maven online repository? Note that i am trying to add several keycloak dependency but not able to find which one has org.keycloak.authentication according to the documentation link: https://www.keycloak.org/docs/3.3/server_ development/topics/auth-spi.html Please help and thanks in advance
