Alfresco LDAP user home path

ccc_chen — Mon, 12 Mar 2012 20:59:36 GMT

My Alfresco connects with LDAP authentication.In the file ldap-authentication.properties, I set defaultHomeFolderProvider = usersHomeFolderProvider, the system creates a LDAP user with user's home directory.Under Alfresco Explorer, if I log on with the LDAP user account, I can see the LDAP user home

Can it be that the home folders are created with "All" permissions (instead of a role like "Coordinator") and CMIS doesn't understand this?

   <bean name="defaultOnCreatePermissionsManager"
      class="org.alfresco.repo.security.person.PermissionsManagerImpl">
      <property name="permissionService">
         <ref bean="permissionServiceImpl" />
      </property>
      <property name="ownableService">
         <ref bean="ownableService" />
      </property>
      <property name="inheritPermissions">
         <value>false</value>
      </property>
      <property name="ownerPermissions">
         <set>
            <value>All</value>
         </set>
      </property>
      <property name="userPermissions">
         <set>
            <value>All</value>
         </set>
      </property>
   </bean>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Try changing this bean (found in authentication-services-context.xml, but do not change directly in this file, create your own myname-context.xml file in extension) and change All to Coordinator.
This will only have effect on newly created folders, to change it for existing you have to do some scripting. If it helps, then you should file an issue att https://issues.alfresco.com.

I am new in alfresco, and have created a myname-context.xml file in tomcat/shared/classes/alfresco/extension, and has changed All to Coordinator.

But, after restart the Alfresco, nothing changed. Is any other thing, what I forgot?

Re: Alfresco LDAP user home path

That looks correct. Just for your information, the file can have any name, as long as it ends with -context.xml.
Note that this will only have an effect on home folders that ar newly created, so that may bee why not immediately see any changes ( and this may not be a the required solution).

On existing user home folder, try adding the user with Coordinator rights by updating the permissions and see if it shows up using CMIS.

Thank you for the answer. I try to reinstall the alfresco, then set the myname-context.xml in the tomcat/shared/classes/alfresco/extension first, and set ldap as (in alfresco-global.properties):

I have created the test-folder in the LDAP-User home directory by Alfresco
but this directory can not see in CMIS, still.
I post the CMIS Test-Code:


public class Testing
{
    public static void main(String args[])
    {
        System.out.println(Testing.class.getName() + " started");

        SessionFactory sessionFactory = SessionFactoryImpl.newInstance();
        Map<String, String> parameter = new HashMap<String, String>();
        
        parameter.put(SessionParameter.USER, "myusername");
        parameter.put(SessionParameter.PASSWORD, "passwd");
        
        parameter.put(SessionParameter.BINDING_TYPE,
                BindingType.ATOMPUB.value());
        parameter.put(SessionParameter.ATOMPUB_URL,
                "http://127.0.0.1:8080/alfresco/service/cmis");

        // get repositories & create session
        try
        {
            List<Repository> repositories = sessionFactory.getRepositories(parameter);
            Repository repository = repositories.get(0);
            Session session = repository.createSession();
            session.getDefaultContext().setCacheEnabled(false);
            
            System.out.println("Got a connection to repository: " + repository.getName() + ", with id: "
                    + repository.getId());
 
            Folder homeFolder = (Folder)session.getObject("workspace://SpacesStore/a358c3e6-1881-4f45-b74f-b7b92f498f9c");
            System.out.println("homeFolder: " + homeFolder.getName());
            ItemIterable<CmisObject> children = homeFolder.getChildren();
            System.out.println("Found the following objects in the root folder:- size: " + children.getTotalNumItems());
        }
        catch (CmisRuntimeException ex)
        {
            ex.printStackTrace();
        }

        System.out.println(Testing.class.getName() + " ended");
    }
}

I use session.getObject(LDAP-userhome-ObjID) get the home folder, but the size of children is zero.

I use the Version 4.0.b
I have checked the right of my LDAP-User by "manage space users", thr roles is Coordinator. But it is not readable still.

I found the solution: set the inheritPermissions=true, then I can read all content of the LDAP-user-folder, as well as the write and execute.

You are welcome. Just notice that now users folders will not be private (depending on permissions on parent folder), but that of course can be exactly what you want.
