Enable LDAPS

The AD Pro Toolkit supports LDAPS on port 636.

What LDAPS is

LDAPS (port 636) refers to LDAP over SSL/TLS, a secure, encrypted version of the Lightweight Directory Access Protocol. It is commonly used to securely communicate with Active Directory Domain Services (AD DS) or other LDAP directories.

Enable LDAPS

  1. Click Settings > Domain Settings.
  2. Edit your connection and select Use LDAPS.
  3. Click Save.

To confirm it is working, take a packet capture in Wireshark between the machine running AD Pro Toolkit and your domain controller. Traffic should now be on port 636 rather than 389.
