I am not sure if the Trusted 3rd party application function is of much value. I have not known anyone to use it. Basically all it is is a user that you define in DocuWare Administration > User Administration > Trusted application users. It is a user name, password, and the file cabinets they have access to. The user still has to login to DocuWare. Frankly, I've never used it and I think it will dissappear.
You can read the Help for it in DocuWare Administration.
