如何使用JavaScript进行LDAP查询？

const ldap = require('ldapjs');

const client = ldap.createClient({
  url: 'ldap://localhost:389',
  bindDN: 'cn=root,dc=example,dc=com',
  bindCredentials: 'secret',
});

const searchOptions = {
  filter: '(objectclass=person)',
  scope: 'sub',
  attributes: ['dn', 'sn', 'cn'],
};

client.search('dc=example,dc=com', searchOptions, (err, res) => {
  if (err) {
    console.error('Error searching:', err);
    return;
  }

  res.on('searchEntry', (entry) => {
    console.log('Entry:', entry.object);
  });

  res.on('error', (err) => {
    console.error('Error:', err);
  });

  res.on('end', () => {
    console.log('Search complete');
  });
});
