   Users can also configure this via **Config XML** tab on the Admin section:
   
  -```
  +~~~ xml
    <security>
         <authConfigs>
           <authConfig id="OpenLDAP" pluginId="cd.go.authentication.ldap">

  At this point, your LDAP server is configured and running. Open up the LDAP port on your firewall so external clients can connect:
  
  ```
  sudo ufw allow ldap
  ```
  
  Let's test our LDAP connection using ldapwhoami, which should return the username we're connected as:
  
  ```
  ldapwhoami -H ldap:// -x
  ```
  
  **Output**
  
  ```
  anonymous
  ```
  
  This should give you “anonymous” as result, since we ran it without logging into the LDAP server. This means the LDAP server is running and responding.
  
  If this gives you connect error something similar to below, try checking the ldap service status **/etc/init.d/slapd** status and restart if it is stopped.
  
  ```
  ldap_sasl_bind(SIMPLE): Can't contact LDAP server (-1)
  ```
  
  Next we'll add a user to the OpenLDAP server and see if we are able to connect.
  
  
  ##Step 2 — Add user to ldap server
  
  Create an add.ldif file and add below content for user details.
  
  ```
  dn: ou=People,dc=gocd,dc=org
  objectClass: organizationalUnit
  ou: People
