前言

因為 JBOSS EAP 8 已經刪除 picketlink 模組，並改用 keycloak-saml 取代，但 keycloak-saml 需要手動自行安裝。

Step1. 下載 keycloak-saml 套件，目前最新版本是 26.1.4。

Step2. 上傳到 /opt 並解壓縮

johnny# unzip -o /opt/keycloak-saml-wildfly-adapter-dist-26.1.4.zip -d keycloak-saml-wildfly-adapter-dist-26.1.4

Step3. 複製套件到 JBOSS 資料夾底下

johnny# cp -R /opt/keycloak-saml-wildfly-adapter-dist-26.1.4/modules/system/add-ons/keycloak/org/keycloak/* /opt/jboss-eap-8.0/modules/system/layers/base/org/keycloak

Step4. 執行安裝 keycloak-saml 設定

johnny# /opt/jboss-eap-8.0/bin/jboss-cli.sh --file=/opt/keycloak-saml-wildfly-adapter-dist-26.1.4/bin/adapter-elytron-install-saml-offline.cli -Dserver.config=standalone.xml

Step5. 修改 standalone.xml
