Java-Aufruf von Active Directory, Apache-Directory-LDAP-API

Ich versuche eine Verbindung zu einer Active Directory von Activiti, Apache Directory-LDAP-API. Ich glaube, ich habe es geschafft, meine Benutzer-Authentifizierung, aber die nachfolgenden Abfragen für die Benutzer nichts findet.

Hier mein Java-code:

public class LDAPUserManager extends UserManager {
    private final static Logger logger = LoggerFactory.getLogger(LDAPUserManager.class);

    private LDAPConnectionParams ldapConnectionParams;

    public LDAPUserManager(LDAPConnectionParams ldapConnectionParams) {
        this.ldapConnectionParams = ldapConnectionParams;
    }

    public Boolean checkPassword(String userId, String password) {
        Boolean result;
        LdapConnection connection;

        String userDN = ldapConnectionParams.getUserPrefix() + "=" +
                userId + "," + ldapConnectionParams.getUserGroup();
        logger.debug("Checking password, using connection string: '" + userDN + "'");
        try {
            connection = openConnection();
            BindResponse bindResponse = connection.bind(userDN, password);
            result = bindResponse.getLdapResult().getResultCode() == ResultCodeEnum.SUCCESS;
        } catch (LdapException e) {
            throw new ActivitiException("LDAP exception while binding", e);
        } catch (IOException e) {
            throw new ActivitiException("IO exception while binding", e);
        }
        //TODO: move this into a finally clause above
        closeConnection(connection);

        return result;
    }

    public List<User> findUserByQueryCriteria(Object o, Page page) {
        List<User> result = new ArrayList<User>();

        UserQueryImpl userQuery = (UserQueryImpl)o;
        StringBuilder queryString = new StringBuilder();
        queryString.append("(").append(ldapConnectionParams.getUserPrefix()).append("=")
                .append(userQuery.getId()).append(")");

        logger.debug("Looking for users: '" + queryString + "'");
        LdapConnection connection;

        try {
            connection = openConnection();
            Cursor<SearchResponse> responseCursor = connection.search(
                    ldapConnectionParams.getUserGroup(), queryString.toString(),
                    SearchScope.ONELEVEL,
                    "cn", "sAMAccountName", "sn");

            logger.debug("Got cursor: " + responseCursor);

            for (SearchResponse response : responseCursor) {
                logger.debug("It's a rsponse: " + response);
            }

            int maxUsers = 10;
            while (responseCursor.next() && maxUsers-- > 0) {
                User user = new UserEntity();
                SearchResultEntry searchResponse = (SearchResultEntry)responseCursor.get();
                logger.debug("Got item: " + searchResponse);
                result.add(user);
            }
            responseCursor.close();
        } catch (LdapException e) {
            throw new ActivitiException("While searching for user in LDAP", e);
        } catch (Exception e) {
            throw new ActivitiException("While searching for user in LDAP", e);
        }
        //TODO: move this into a finally clause above
        closeConnection(connection);
        logger.debug("Returning users: " + result);
        return result;
    }

    private void closeConnection(LdapConnection connection) {
        try {
            connection.unBind();
        } catch (Exception e) {
            e.printStackTrace();
        }
        try {
            connection.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    private LdapConnection openConnection() throws LdapException, IOException {
        LdapConnection connection = new LdapConnection(
                ldapConnectionParams.getLdapServer(),
                ldapConnectionParams.getLdapPort()) {

            public void exceptionCaught(IoSession ioSession, Throwable throwable) throws Exception {
                logger.error("Exception thrown in " + ioSession, throwable);
            }
        };
        connection.connect();
        return connection;
    }

}

Ich Las ein paar Sachen aus der spring-bean-Definitionen:

<property name="ldapServer" value="secret"/>
<property name="ldapPort" value="389"/>
<property name="ldapUser" value="CN=Stefan Blixt,OU=x,OU=x,OU=x,DC=x,DC=x"/>
<property name="ldapPassword" value="secret"/>
<property name="userGroup" value="OU=x,OU=x,OU=x,DC=x,DC=x"/>
<property name="userPrefix" value="CN"/>

Activiti wird zuerst ausgeführt checkPassword(), welche true zurückgibt, dann wird es laufen findUserByQueryCriteria(), die Ausgänge dieser:

DEBUG: com.abc.activiti.ldap.LDAPUserManager - Looking for users: '(CN=Stefan Blixt)'
DEBUG: com.abc.activiti.ldap.LDAPUserManager - Got cursor: org.apache.directory.ldap.client.api.SearchCursor@1e3940a
DEBUG: com.abc.activiti.ldap.LDAPUserManager - Returning users: []

Ich es geschafft habe zu verbinden und diese Art der Abfrage in Apache Directory Studio:

Dass man mir ein Ergebnis mit dem Eintrag für Stefan Blixt.

Habe ich bearbeitet, einige Pfade, die oben für die Privatsphäre.

Irgendwelche Ideen? Gibt es irgendwelche Klassiker die Täter, die möglicherweise in null-Ergebnis Ergebnisse, wenn dabei eine LDAP-user-Suche? Ich habe versucht, mit "uid", "sAMAccountName" etc. bei der Suche - immer das gleiche Ergebnis.
