LMC LDAP Setup Error using Windows Server 2012 with SSL/TLS


To resolve this issue, the certificate(s) of Windows Server 2012 LDAP need to be added in every tomcat/application server.

1 Export the certificates (*.cer files) from Windows Server 2012 using Microsoft Management Console (MMC), to a folder on the Lexmark Document Distributor (LDD) server machine.
2 Press the Win key + R on your keyboard to open the Run box and open a command prompt window by typing in cmd.

Go to the LDD Java directory on a tomcat server, which is usually located in C:\Program Files\Lexmark\Solutions\jre\bin, and type;

keytool -import -alias %ALIAS%-storepass changeit -keystore ..\lib\security\cacerts -file %FILE_PATH%

  • %ALIAS% – is a string that can be anything. It just needs to be unique.
  • %FILE_PATH% – is where you move the copied certificate(s).
    Use double quotes ("") around the path if it contains spaces.
  • changeit – is the default Java JRE keystore password.

For example, %ALIAS% = vg3c3inter, %FILE_PATH% = c:\temp dir\VerisignG3Class3-Inter.cer, and changeit remains as a default:

keytool -import -alias vg3c3inter -storepass changeit -keystore ..\lib\security\cacerts -file "c:\temp dir\VerisignG3Class3-Inter.cer"

Important! Do this for all of the certificates that were copied.


To verify whether the certificates were added, run the list command by typing in the following string.

keytool -list -storepass changeit -keystore ..\lib\security\cacerts

5 Perform Steps 34 for all tomcat/application servers in the LDD System.
