AEM 6.1 - Unlocking pages issue having resolverFactory.getServiceResourceResolver() approach

Question

In a project that I am working in AEM 6.1, we are using the "new" way to obtain a valid ResourceResolver object through the line resolverFactory.getServiceResourceResolver(). As you know, is neccessary to have a System User created with the right permissions in the environment, to perform some tasks in the JCR. We have created a System User with Admin rights.

Attach of the permissions: useradmin page

This user is assigned to the Apache Sling Service User Mapper Service config as a Default User, so we do not have to pass anytime in the code the Map object with the subservice name. The page path that I am testing is /content/test/test-1/test-folder/test-unlock-page/. Attached the related CODE. When the line page.unlock() is executed this throws a WCMException

    @Override
public void unlock(String userId, String pagePath) throws LoginException, WCMException {        

    ResourceResolver resourceResolver =resourceResolverFactory.getServiceResourceResolver(null);
    PageManager pageMgr = resourceResolver.adaptTo(PageManager.class);
    Session session = resourceResolver.adaptTo(Session.class);
    Page page = pageMgr.getPage(pagePath);

    if(!page.isLocked()) {
        log.info("Page is NOT locked, unlock operation not mandatory: " + pagePath);
    } else {
    log.info("Unlocking page on behalf of: " + userId);
    page.unlock();
}

The exception cause is:

javax.jcr.lock.LockException: Not an owner of the lock /content/test/test-1/test-folder/test-unlock-page/jcr:content

I read the documentation of this link and according my understanding when you specify a modify permission for this user the user can lock (locking) but this paragraph does not tell anything about unlocking:

At the JCR level, users can modify a resource by modifying its properties, locking, versioning, nt-modifications, and they have complete write permission on nodes defining a jcr:content child node, for example cq:Page, nt:file, cq:Asset

I am thinking if is possible to assign in other place a permission to unlock to this System user, because it seems that is imposible to do it with the current privileges.

Thanks for any idea about it.

Answer 1

It is not possible. only the admin user and lock owner can remove the lock.
