从TDS LDAP获取所有用户，包括图像

Question

我使用下面的代码使用Java API从TDS LDAP中检索所有用户。但是当我在返回属性中包含图像时，查询不起作用。请帮我解决。

String returnedAtts[] = {"jpegPhoto","cn","uid","UserAccountStatus"};

当我包含属性“jpegPhoto”时，我的结果是空的。

但没有属性“jpegPhoto”，如下所示，我得到所有用户data.i需要所有用户的图像也因此查询（cn = *）不使用图像属性。

String returnedAtts[] = {"uid","cn","UserAccountStatus"};



try {
        // Create the initial directory context
        DirContext ctx = new InitialLdapContext(env,null);
        //Create the search controls   
        SearchControls searchCtls = new SearchControls();
        //Specify the attributes to return
        String returnedAtts[]={"jpegPhoto","DateofBirth","DateofJoining","cn","sn","UserAccountStatus","uid"};
                //String returnedAtts[]={"DateofBirth","DateofJoining","cn","sn","UserAccountStatus","uid"};
        searchCtls.setReturningAttributes(returnedAtts);
        //Specify the search scope
        searchCtls.setSearchScope(SearchControls.SUBTREE_SCOPE);

                String searchBase = "cn=parleRealm,o=parle";

        int totalResults = 0;
        // Search for objects using the filter
        NamingEnumeration answer = ctx.search(searchBase, "(&(objectClass=inetOrgPerson)(cn=*))", searchCtls);

                while (answer.hasMoreElements()) {

                SearchResult sr = (SearchResult)answer.next();
                totalResults++;

                // Print out some of the attributes, catch the exception if the attributes have no values
                Attributes attrs = (Attributes) sr.getAttributes();
                if (attrs != null) {
                    try {
                        if("Active".equals(attrs.get("UserAccountStatus").get().toString())){

                        /*   
                        ub=new UserBean();
                        ub.setUid((String)attrs.get("uid").get());
                        ub.setCn((String)attrs.get("cn").get());
                        ub.setSn((String)attrs.get("sn").get());
                        ub.setDateOfBirth((String)attrs.get("DateofBirth").get());
                        ub.setDateofJoining((String)attrs.get("DateofJoining").get());
                        list.add(ub);*/


                      System.out.println(attrs.get("cn").get());      
                    }
                    }
                catch (Exception e) {
                      System.out.println(attrs.get("uid").get()+"is failed to read");
                    }
                }
            }

我在使用java api从TDS ldap获取所有用户数据时遇到错误。

我的代码是

try {
        // Create the initial directory context
        DirContext ctx = new InitialLdapContext(env,null);
        //Create the search controls   
        SearchControls searchCtls = new SearchControls();
        //Specify the attributes to return
        String returnedAtts[]={"jpegPhoto","cn","sn","UserAccountStatus","uid"};
                //String returnedAtts[]={"jpegPhoto","DateofBirth","DateofJoining","cn","sn","UserAccountStatus","uid"};
        searchCtls.setReturningAttributes(returnedAtts);
        //Specify the search scope
        searchCtls.setSearchScope(SearchControls.SUBTREE_SCOPE);

                String searchBase = "cn=parleRealm,o=parle";

        int totalResults = 0;
        // Search for objects using the filter
        NamingEnumeration answer = ctx.search(searchBase, "(&(objectClass=inetOrgPerson)(cn=r*))", searchCtls);

                while (answer.hasMoreElements()) {

                SearchResult sr = (SearchResult)answer.next();
                totalResults++;

                // Print out some of the attributes, catch the exception if the attributes have no values
                Attributes attrs = (Attributes) sr.getAttributes();
                if (attrs != null) {
                    try {
                        if("Active".equals(attrs.get("UserAccountStatus").get().toString())){

                        /*   
                        ub=new UserBean();
                        ub.setUid((String)attrs.get("uid").get());
                        ub.setCn((String)attrs.get("cn").get());
                        ub.setSn((String)attrs.get("sn").get());
                        ub.setDateOfBirth((String)attrs.get("DateofBirth").get());
                        ub.setDateofJoining((String)attrs.get("DateofJoining").get());
                        list.add(ub);*/


                      System.out.println(attrs.get("jpegPhoto").get() + ">>> cn >> " + attrs.get("cn").get());      
                    }
                    }
                catch (Exception e) {
                      System.out.println(e);
                     // System.out.println(attrs.get("uid").get()+"is failed to read");
                    }
                }
            }

但如果我删除＆＃34; jpegPhoto＆＃34;我将获取所有用户数据返回属性。
