Uploading the DC Certificate (optional)
You can upload multiple DC certificates. Upload a certificate that permits LDAP over SSL.
- Click the Upload Certificate Tab.
  
- Obtain the certificate from the DC by opening a new web browser window to https://<domain_controller>:636 (where domain_controller is your DC). Note that this is a secure HTTPS URL, so you are prompted to accept a certificate. Click View Certificate.
  
- Click the Details tab, and then click Copy to File.
  
- Select Base-64 encoded x.509 (.CER) from the list of export options (this is important). Provide a name and location for the file (c:dccert.cer) and finish the wizard.
  
- Locate the exported certificate file in explorer and rename it with a .txt extension (dccert.txt). Open the file in notepad and copy the entire contents to the clipboard. The following is an example of the certificate file contents:
