See below for enabling SSL in an existing JNDIDirectory connection.

Selecting the SSL certificates

Get Trusted SSL X509 Certificates from the location of your choice

X509Certificate trustedcerts[] = 
(X509Certificate[])certlist.toArray(new X509Certificate[]{});

Create an LDAPSConfig object to specify the SSL parameters.

LDAPSConfig sslconfig = new LDAPSConfig(true);

Where true enables LDAP over SSL using the following scheme.

ldaps://

Specify the trusted SSL certificates.

sslconfig.addTrustCerts(trustedcerts);

Setting the SSL configuration

Create the JNDIDirectory object either in the usual manner:

JNDIDirectory dir= new JNDIDirectory(directory,Integer.parseInt(port));

...or with the new constructor;

JNDIDirectory dir = new JNDIDirectory("ldaps://myLDAPSHost.com:636");

Set the SSL configuration.

dir.setLDAPSConfig(sslconfig);
