I'm a newbie using WSO2 IS 5.0.0 and ESB 4.8.1, trying out this example @ http://hasini-gunasinghe.blogspot.sg/2011/08/fine-grained-authorization-to-restful.html (had changed xacml 2.0 to 3.0 policy, published policy to PDP) Had also referred to https://malalanayake.wordpress.com/2013/02/13/authentication-and-authorization-with-wso2esb-and-wso2is/

In user-mgmt.xml of ESB, had set AddAdmin to false, comment the org.wso2.carbon.user.core.jdbc.JDBCUserStoreManager section and uncomment the ISUserStoreManager class="org.wso2.carbon.user.core.ldap.ReadWriteLDAPUserStoreManager" section and restart ESB

However, it is throwing [Start Level Event Dispatcher] ERROR Activator Cannot start User Manager Core bundle java.lang.NullPointerException at org.wso2.carbon.user.core.common.DefaultRealmService.(DefaultRealmService.java:87) at org.wso2.carbon.user.core.common.DefaultRealmService.(DefaultRealmService.java:114) at org.wso2.carbon.user.core.internal.Activator.startDeploy(Activator.java:69) at org.wso2.carbon.user.core.internal.BundleCheckActivator.start(BundleCheckActivator.java:61) at org.eclipse.osgi.framework.internal.core.BundleContextImpl$1.run(BundleContextImpl.java:711) at java.security.AccessController.doPrivileged(Native Method) at org.eclipse.osgi.framework.internal.core.BundleContextImpl.startActivator(BundleContextImpl.java:702) at org.eclipse.osgi.framework.internal.core.BundleContextImpl.start(BundleContextImpl.java:683) at org.eclipse.osgi.framework.internal.core.BundleHost.startWorker(BundleHost.java:381) at org.eclipse.osgi.framework.internal.core.AbstractBundle.resume(AbstractBundle.java:390) at org.eclipse.osgi.framework.internal.core.Framework.resumeBundle(Framework.java:1176) at org.eclipse.osgi.framework.internal.core.StartLevelManager.resumeBundles(StartLevelManager.java:559) at org.eclipse.osgi.framework.internal.core.StartLevelManager.resumeBundles(StartLevelManager.java:544) at org.eclipse.osgi.framework.internal.core.StartLevelManager.incFWSL(StartLevelManager.java:457) at org.eclipse.osgi.framework.internal.core.StartLevelManager.doSetStartLevel(StartLevelManager.java:243) at org.eclipse.osgi.framework.internal.core.StartLevelManager.dispatchEvent(StartLevelManager.java:438) at org.eclipse.osgi.framework.internal.core.StartLevelManager.dispatchEvent(StartLevelManager.java:1) at org.eclipse.osgi.framework.eventmgr.EventManager.dispatchEvent(EventManager.java:230) at org.eclipse.osgi.framework.eventmgr.EventManager$EventThread.run(EventManager.java:340)

Pls assist. Thanks

So, you want to configure ESB to connect to the LDAP user store of the WSO2IS. Then you want to go through followings. (Please note ESB does not contain embedded LDAP server.)

  1. Comment the org.wso2.carbon.user.core.jdbc.JDBCUserStoreManager

  2. Uncomment ISUserStoreManager

  3. Rename the ISUserStoreManager tag in to UserStoreManager

  4. Configure the LDAP url in to WSO2IS server's LDAP url. You can do it by configuring following property under UserStoreManager element. By default LDAP port of WSO2IS is 10389 (with port offset 0)

    <Property name="ConnectionURL">ldap://localhost:10389</Property>

Also, if you are using WSO2IS for XACML authorization, I would suggest for you to go through this blog as it contain all basic for to work with XACML in WSO2IS.
