Custom Workflow Component - Iterate over Users

[crich2784]

I have a custom workflow component that needs to look up a User in the AEM User repository.

Code is pretty simple:

resourceResolver = getResourceResolver(workflowSession);
UserManager userManager = resourceResolver.adaptTo(UserManager.class);
Iterator<Authorizable> userIterator = userManager.findAuthorizables("jcr:primaryType", "rep:User");
Iterator<Authorizable> groupIterator = userManager.findAuthorizables("jcr:primaryType", "rep:Group");
while (userIterator.hasNext()) {
   log.info("Getting user");
   Authorizable user = userIterator.next();
   if (!user.isGroup()) {
      log.info("User found: {}", user.getID());
   }
}

The output only finds "anonymous" user.  Is it a permissions issue?  How do I allow it to iterate through ALL users in AEM?

Hi @crich2784 

How are you getting the resource resolver? 

I just tried the below snippet on my instance and it gives me the complete list of users. I am retriving the resource resolver from workflow session.

I hope you are using "com.adobe.granite.workflow" API.

import com.adobe.granite.workflow.WorkflowSession;
import com.adobe.granite.workflow.exec.WorkItem;
import com.adobe.granite.workflow.exec.WorkflowProcess;
import com.adobe.granite.workflow.metadata.MetaDataMap;
import org.apache.jackrabbit.JcrConstants;
import org.apache.jackrabbit.api.security.user.Authorizable;
import org.apache.jackrabbit.api.security.user.UserManager;
import org.apache.jackrabbit.oak.spi.security.user.UserConstants;
import org.apache.sling.api.resource.ResourceResolver;
import org.osgi.service.component.annotations.Component;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import javax.jcr.RepositoryException;
import java.util.Iterator;

@Component(service = WorkflowProcess.class, property = {"process.label=Get All User Process"})
public class GetAllUserWorkflowProcess implements WorkflowProcess {

    private static final Logger log = LoggerFactory.getLogger(GetAllUserWorkflowProcess.class);

    @Override
    public void execute(WorkItem workItem, WorkflowSession workflowSession, MetaDataMap metaDataMap) {
        log.info("***** :: execute :: Start :: *****");
        try (ResourceResolver resourceResolver = workflowSession.adaptTo(ResourceResolver.class)) {
            final UserManager userManager = resourceResolver.adaptTo(UserManager.class);
            if (null != userManager) {
                Iterator<Authorizable> userAuthorizables = userManager.findAuthorizables(JcrConstants.JCR_PRIMARYTYPE, UserConstants.NT_REP_USER);
                userAuthorizables.forEachRemaining(user -> {
                    log.info("Getting User...");
                    try {
                        String id = user.getID();
                        log.info("User ID -> {}", id);
                    } catch (RepositoryException e) {
                        log.error("Error While getting User", e);
                    }
                });
            }
        } catch (RepositoryException repoException) {
            log.error("Error", repoException);
        }
        log.info("***** :: execute :: End :: *****");
    }
}

Here is the output I get in log with the user details. Could not put all here due to character restrictions.

I actually got it working with very similar code. It was a permissions thing. I figured out how to whitelist my component but, ultimately I need to set up a service account becasue loginAdministrative() is deprecated. I need to find some easy instructions for a service account.

[crich2784]

I figured this out . . . the code was working as expected.  I went into configmgr and whitelisted all components and it worked.  The code, right or wrong, is working.  

Now I need to figure out a service account and not use the whitelisting.
