Re: [keycloak-user] NullPointerException when attempting to remove group

Hello, I'm getting the following error when I attempt to delete a group that has been imported from a FreeIPA LDAP User Federation through a group-ldap-mapper: 2017-08-04 16:46:21,636 ERROR [io.undertow.request] (default task-16) UT005023: Exception handling request to /auth/admin/realms/authentid/ groups/e2a3cd4a-c4f4-4b9e-bb51-d9782d40aae0: org.jboss.resteasy.spi.UnhandledException: java.lang.NullPointerException at org.jboss.resteasy.core.ExceptionHandler.handleApplicationException( ExceptionHandler.java:76) at org.jboss.resteasy.core.ExceptionHandler.handleException( ExceptionHandler.java:212) at org.jboss.resteasy.core.SynchronousDispatcher.writeException( SynchronousDispatcher.java:168) at org.jboss.resteasy.core.SynchronousDispatcher.invoke( SynchronousDispatcher.java:411) at org.jboss.resteasy.core.SynchronousDispatcher.invoke( SynchronousDispatcher.java:202) at org.jboss.resteasy.plugins.server.servlet.ServletContainerDispatcher. service(ServletContainerDispatcher.java:221) at org.jboss.resteasy.plugins.server.servlet.

There are two LDAP User Federations setup, one to an Active Directory, one to the aforementioned FreeIPA instance. Both have group mappers setup and some of the group names clash unfortunately, that's why I wanted to delete some groups and redo the import. What can I do? -- Tiemen Ruiten Systems Engineer R&D Media
