Reading DRM protected PDF files..

[cepwin]

I have a set of DRM protected PDF files that I read on my PC but the adobe app on android doesn't seem to support DRM protection. Instead of prompting me for my username and password as it does on the PC it just tells me it can't be read. I've tried several PDF readers, some even read password protected files but the results are the same...they can't be read. Are there any PDF readers that do handle DRM protected files??? I have legitimate access to these files (this is training material I purchased) and it would make things a lot easier if I could look at them on my tablet and phone which are both android.
