+            The Keycloak Spring Security adapter also supports multi tenancy. Instead of injecting
+            <literal>AdapterDeploymentContextFactoryBean</literal> with the path to <literal>keycloak.json</literal> you
+            can inject an implementation of the <literal>KeycloakConfigResolver</literal> interface. More details on how
+            to implement the <literal>KeycloakConfigResolver</literal> can be found in <xref linkend="multi_tenancy" />.
