AEM 6.1 ResourceResolver

[olegd52630483]

This does not work:

private ResourceResolver getImpersonatedResolver(String userId) { Map<String, Object> param = new HashMap<>();    try {if(StringUtils.isNotBlank(userId)){ param.put(ResourceResolverFactory.USER_IMPERSONATION, userId);            return resourceResolverFactory.getResourceResolver(param);        } } catch (Exception e) {log.error(e.getLocalizedMessage(), e);    }return null;}

The following exception message appears:

Impersonation not allowed.
org.apache.sling.api.resource.LoginException: Impersonation not allowed.
    at org.apache.sling.jcr.resource.internal.helper.jcr.JcrResourceProviderFactory.getLoginException(JcrResourceProviderFactory.java:402)

    at org.apache.sling.resourceresolver.impl.ResourceResolverFactoryImpl.getResourceResolver(ResourceResolverFactoryImpl.java:99)

Under AEM 6.0 it worked.

It looks like logged in User doesnt have permission to impersonate the given userId. 

Have you configured the same for the logged in User in useradmin ?

 I do see the same problem at the last line, it is throwing the same exception

we have created writeService system user and added to administrators group (AEM 6.2)

Map<String, Object> param = new HashMap<String, Object>();        
                param.put(ResourceResolverFactory.SUBSERVICE, "writeService");
            adminResolver = resourceResolverFactory.getServiceResourceResolver(param);
            adminSession = adminResolver.adaptTo(Session.class);

userSession = adminSession.impersonate(new SimpleCredentials(member.getID(),"".toCharArray()));
