To connect DualShield to Active Directory via LDAP over SSL (LDAPS), you must tell your DualShield server to trust your AD server. In other words, you must import the CA certificate that was used to sign the server certificate of your AD server into the keystore of your DualShield server as a trusted root certificate.

Configure Active Directory Authentication with LDAP over SSL

First of all, make sure that your AD server is fully configured to accept SSL connection. To verify that your AD server is enabled with LDAPS connection, you can run a Microsoft support tool LDP.EXE on your AD server. You should see the following output:

      

If your AD server is not yet configured to accept SSL connection, then you must first enable the SSL connection. The article below has detailed instructions of how to Configure Active Directory Authentication with LDAP over SSL:

Import CA Certificate into DualShield

Next, you need to import the CA certificate into your DualShield's keystore. DualShield's keystore is a JAVA keystore and there is a tool included in the DualShield that can be used to import certificates. Follow the steps below:

  1. navigate to "tools" folder in your DualShield directory, e.g. C:\Program Files\Deepnet DualShield\tools
  2. unzip "portecle.zip"
  3. navigate to the Portecle folder, e.g. C:\Program Files\Deepnet DualShield\tools\portecle-1.7\portecle-1.7
  4. open Windows CMD console
  5. execute "portecle.jar", e.g. ..\..\..\jre\bin\java -jar portecle.jar

      

you should now see the Portecle's user interface:

...

  1. Select "File | Open CA Certs Keystore"
  2. Enter the default password: "changeit"
  3. Select "Tools | Import Trusted Certificate" and import your CA certificate

Mind you, Please note that if you can double click the file portecle.jar to run this utility, then it is very likely that you have another JRE installed on this machine . Generally this JRE that is NOT the one we used in DualShield. In that case, please choose the menu "Open Keystore File..." instead, then locate the file "cacerts" under DualShield installation folder.

Alternatively, you can import a root or intermediate CA certificate to an existing Java keystore with following command
