If you are using the edrn singlesignon Java package to authenticate against the LDAP server running on cancer, you will need to have a correct certificate installed onto your JDK.  To generate the certificate:

  1. Compile the package, including InstallCert.java in edrn/security/certs
  2. Pull the certificate down by running
    java InstallCert cancer.jpl.nasa.gov:636

    which will create a file called jssecacerts in the working directory.

  3. Copy this file to JDK/lib/security folder
