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.
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, enter the server name, and connection port as "636".
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:
Once your AD server is configured to accept LDAPS connection, you need to export the CA certificate from your AD server.
The CA used to sign the LDAPS certificate is not necessary to be the one of your Certification Authority, so the safe way to locate the CA is to follow the steps below.
First, you need to find the SSL certificate of the AD server. There are 2 ways:
Normally it has "DomainController" as its Certificate Template Name.
The Active Directory fully qualified domain name of the domain controller (for example, povm2k3svr.parkoffice.com) must appear in one of the following places:
Download openssl and run the following command.
openssl s_client -connect myldapsserver.domain.com:636
Part of the output of this file will be the Base-64 encoded .cer file that was presented for LDAPS. Just cut and paste into notepad beginning at "--Begin Certificate--" through "---End Certificate---" and save as a .cer Double-click on the certificate file and you will now be viewing the certificate presented for LDAPS.
Once you have found the SSL certificate of the AD server, double click the certificate, go to the tab "Cetification Path"
In our example, the CA to sign the LDAPS certificate is the highlighted one "ca".
To export the CA certificate:
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:
you should now see the Portecle's user interface:
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 that is NOT the one 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
C:\Program Files\Deepnet DualShield\jre\bin\keytool -import -trustcacerts -alias root -file yourca.crt -keystore C:\Program Files\Deepnet DualShield\jre\lib\security\cacerts
Once you have successfully import your AD's CA certificate into your DualShield's keystore, restart the DualShield server.
Finally, in DualShield, modify the LDAP connection of your Identity Source that's connected to your AD server.
