I've used Adobe Document Center to protect pdf files by disabling printing and copying, and setting expiration for 14 days.
That works great for my purposes, but my clients (end users) are having trouble opening these files. They register with adobe.com, their IDs and passwords work fine in adobe.com, and yet it always tells them that their ID or password is incorrect when they try to open a protected pdf.
The only way they can open the protected pdf files I send them is to register for the Adobe Document Center free trial first. They only want to open the files, and registering for some kind of free trial scares them off.
I think that only an Adobe.com registration is supposed to be required. Nowhere is there any information that says the end user needs to register for Adobe Document Center also.
Any info on this would be very helpful. Thanks.

ADC is a public beta service provided without charge, and so there is a natural amount of product promotion involved during the registration process. The same is true of any other free-to-use web service. ADC attempts to make it as quick and simple as possible, but it is not intended to be a production platform.
If you wish to operate a Policy Server system that follows different rules, you'll need to buy your own copy or rent accounts from a service provider - but users will still need to be registered on the server before they can access the files, and handling all that yourself can be a lot of work.
