Test Connection on LDAP Connection Profile Wizard page does not enable

Filling in required info in new LDAP connection profile does not enable the "Test Connection" button.

Looks like a "setPingButtonEnabled(true);" call needs to be made at the end of the LdapProfileDetailsWizardPage.validate() method, but adding the code ends up throwing an NPE when pressed.

So, it looks like there is no IConnectionFactoryProvider/IConnectionFactory contributed for the LDAP connection to use to "ping" the DB. This would have to be completed in order for the Test Connection button to not throw an NPE
