title: How to retrieve all LDAP attributes definition on LDAP database?
body: <p>I'm working with ldap and want to retrieve all Ldap Attribute fields that defined on Ldap server. I just need list of attribute field only not the value. The result should be a list like this:</p>
  
  <pre><code>['mailNickname',
   'publicDelegatesBL',
   'logonCount',
   'cn',
   'countryCode',
   'dSCorePropagationData',
   'objectClass',
   # ...
  'telephoneNumber',
  'physicalDeliveryOfficeName',
  'name',
  'memberOf',
  'codePage',
  'userAccountControl',
  'msExchMDBRulesQuota',
  'lastLogon',
  'protocolSettings',
  'uSNChanged',
  'sn',
  'msExchVersion',
  'mDBUseDefaults',
  'givenName',
  'msExchMailboxGuid',
  'lastLogoff']
  </code></pre>
  
  <p>Is there way to do this?</p>
