Hello, I'm using Keycloak 3.4.0.Final. I have an EAR containing a WAR. The WAR contains REST services that I need to secure. The Wildfly config is as follows: <subsystem xmlns="urn:jboss:domain:keycloak:1.1"> <secure-deployment name="customer-management.ear.customer-management-rest.war"> <realm>demo</realm> <auth-server-url> <http://localhost:18080/auth> http://localhost:18080/auth</auth-server-url> <public-client>true</public-client> <ssl-required>EXTERNAL</ssl-required> <resource>customer-client</resource> </secure-deployment> </subsystem> The notation I used for the <secure-deployment> element is ear-name.ear.war-name.war. But it doesn't seem to work. It raises the following exception: Caused by: org.jboss.as.server.deployment.DeploymentUnitProcessingException: WarMetaData not found for customer-management.ear. Make sure you have specified a WAR as your secure-deployment in the Keycloak subsystem."}, I found this syntax by googling for solutions but it's probably wrong. Please notice that I cannot used the JSON syntax. Kind regards, Nicolas DUMINIL
