Hello, i'm facing the problem with LDAP import task. I have succesfully configured task to import users and groups from Active Directory and everything seems to be OK until I tried to login with imported user.
Following frontend exception is throw:

I found that mandatory "home space" attribute of each imported users is missing. I tried some changes in configuration (companyHomeFolderProvider) but without success. Could anybody help me? Thanks

Here is my LDAP config:

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE beans PUBLIC '-//SPRING//DTD BEAN//EN' 'http://www.springframework.org/dtd/spring-beans.dtd'>

<beans>
     
    <!– 
    This bean is used to support general LDAP authentication. It is also used to provide read only access to users and groups
    to pull them out of the LDAP reopsitory  
    –>
  
    <bean id="ldapInitialDirContextFactory" class="org.alfresco.repo.security.authentication.ldap.LDAPInitialDirContextFactoryImpl">
        <property name="initialDirContextEnvironment">

                </entry>
              
                <!– The url to the LDAP server –>
                <entry key="java.naming.provider.url">
                    <value>ldap://ibmserver:389</value>
                </entry>
              
                <!– The authentication mechanism to use      –>
                <!– Some sasl authentication mechanisms may require a realm to be set –>
                <!–                java.naming.security.sasl.realm –>
                <!– The available options will depend on your LDAP provider –>
                <entry key="java.naming.security.authentication">
                    <value>simple</value>
                </entry>
              
                <!– The id of a user who can read group and user information –>
                <!– This does not go through the pattern substitution defined above and is used "as is" –>
                <entry key="java.naming.security.principal">
                    <value>cn=Jet Speed,ou=Jetspeed,ou=beez,DC=Company,DC=com</value>
                </entry>
              
                <!– The password for the user defined above –>
                <entry key="java.naming.security.credentials">
                    <value>Asdfghjkl1234</value>
                </entry>
            </map>
        </property>
    </bean>
  
    <!– Ldap Syncronisation support –>
  
    <!–
      
    There can be more than one stack of beans that import users or groups. For example, it may be easier
    to have a version of ldapPeopleExportSource, and associated beans, for each sub-tree of your ldap directory
    from which you want to import users. You could then limit users to be imported from two or more sub tress and ignore
    users found else where. The same applies to the import of groups.
        
    The defaults shown below are for OpenLDAP.  
      
    –>
      
  
    <!– Extract user information from LDAP and transform this to XML –>
    
    <bean id="ldapPeopleExportSource" class="org.alfresco.repo.security.authentication.ldap.LDAPPersonExportSource">
        <!–
        The query to select objects that represent the users to import.
      
        For Open LDAP, using a basic schema, the following is probably what you want:
        (objectclass=inetOrgPerson)
      
        For Active Directory:
        (objectclass=user)
        –>
        <property name="personQuery">
            <value>(objectclass=organizationalPerson)</value>
        </property>
      
        <!–
        The seach base restricts the LDAP query to a sub section of tree on the LDAP server.
        –>
        <property name="searchBase">
            <value>cn=Users,dc=Company,dc=com</value>
        </property>
      
        <!–
        The unique identifier for the user.
      
        THIS MUST MATCH WHAT THE USER TYPES IN AT THE LOGIN PROMPT  
      
        For simple LDAP authentication this is likely to be "cn" or, less friendly, "distinguishedName"
      
        In OpenLDAP, using other authentication mechanisms "uid", but this depends on how you map
        from the id in the LDAP authentication request to search for the inetOrgPerson against which
        to authenticate.
      
        In Active Directory this is most likely to be "sAMAccountName"
      
        This property is mandatory and must appear on all users found by the query defined above.
      
        –>
        <property name="userIdAttributeName">
            <value>sAMAccountName</value>
