If you refer to section 06.02 in the Wiki titled, "Directory Services Authentication, " you'll find direction on creating a directory service and an example. You will just copy and paste the example into a text editor such as notepad++ and import it the same way you would would any other entity. This will be the entity you duplicate in composer.
Once I have the Directory Service configured, do I need to do anything to associate it to the users? My understanding was once I've configured and enabled the Directory Service, Thingworx would automatically attempt to authenticate against the Directory Services available. The security logs seem to indicate it is authenticating against the Thingworx password set for the user.
"Authentication attempt #1 FAILED for [user = com.thingworx.security.users.User@5e1b5726 ]: Invalid Password"
Also is there a way to test to see if my configuration settings are correct in the Directory Service?
