Ldap syn doesnt work properly !! pls pls help

Question asked by blc on Mar 25, 2008
Hi all,

I am using:
1. Windows Server 2003
2. Alfresco 2.1
3. Active Directory (for ldap sync)

I have configured ldap syn with AD, users and groups can be exported and imported. However, there are problems as belows:
1. the newly imported groups dont include users (the groups have users inside in AD)
2. the newly imported users cannot login to Alfresco using WEB UI and the error as below:
15:07:38,406 ERROR [org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/alfresco].[Faces Servlet]] Servlet.service() for servlet Faces Servlet threw exception
java.lang.IllegalArgumentException: nodeRef is a mandatory parameter….
3. the newly imported users does not have their user home folder created (not sure is this related to the login problem in point 2)

and the configuration file I have amended as belows:

1. ldap-authentication-context.xml

    <!– LDAP authentication configuration –>

    <!–

    You can also use JAAS authentication for Kerberos against Active Directory or NTLM if you also require single sign on from the
    web browser. You do not have to use LDAP authentication to synchronise groups and users from an LDAP store if it supports other
    authentication routes, like Active Directory.

    –>

    <bean id="authenticationComponentImpl" class="org.alfresco.repo.security.authentication.ldap.LDAPAuthenticationComponentImpl">
        <property name="LDAPInitialDirContextFactory">
            <ref bean="ldapInitialDirContextFactory"/>
        </property>
        <property name="userNameFormat">
      
            <!–

            This maps between what the user types in and what is passed through to the underlying LDAP authentication.

            "%s" - the user id is passed through without modification.
            Used for LDAP authentication such as DIGEST-MD5, anything that is not "simple".

            "cn=%s,ou=London,dc=company,dc=com" - If the user types in "Joe Bloggs" the authentricate as "cn=Joe Bloggs,ou=London,dc=company,dc=com"
            Usually for simple authentication.
–>

        </property>
    </bean>

    <!–

    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">

                <entry key="java.naming.security.authentication">

            </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=user)</value>
        </property>

        <!–
        The seach base restricts the LDAP query to a sub section of tree on the LDAP server.
        –>
        <property name="searchBase">
            <value>OU=Alfresco,DC=a,DC=b,DC=c</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>
        </property>

        –>
        <property name="userIdAttributeName">
            <value>sAMAccountName</value>
        </property>

        <!–
        An attribute that is a unique identifier for each group found.
        This is also the name of the group with the current group implementation.
        This is mandatory for any groups found.

        <property name="groupIdAttributeName">

        <!–
        The objectClass attribute for group members.
