[Apiman-user] Production deployment questions

Hi - I'm working through the production deployment guide and have a few questions concerning the standalone-apiman.xml file. In the file, I see several entries like this (one each for apiman.war, apimanui.war, and apiman-gateway-api.war). <kc:secure-deployment xmlns:kc="urn:jboss:domain:keycloak:1.0" name="apiman.war"> <kc:realm>apiman</kc:realm> <kc:resource>apiman</kc:resource> <kc:credential name="secret">password</kc:credential> 1. Is "password" supposed to be replaced by some credential? This isn't mentioned in the instructions; my guess is that this credential is used only for applications that request REST Direct Access Grants, and that apiman doesn't. Is that correct? 2. If I'm configuring the gateway as a separate service, can I remove the apimanui.war secure-deployment entry? Correspondingly, when I configure the standalone API manager, do I remove the apiman-gateway-api.war entry? 3. Is it possible to set properties that appear in apiman.properties by way of Java system properties or in a <system-properties> configuration in the standalone-apiman.xml file?
