ASP CheckAuthentication

Hi everybody and thanks in advance for giving me your attention, first of all.

Well, I'm kinda mad about this: I've upgraded from FCKeditor to CKEditor+CKFinder. I'm on a Windows+ASP platform. So far I'm fine with the new software: better text formatting, better code handling, etc... but I can't get the file/upload browser to work properly. Everytime I click on "browse" it says that the file browser is disabled due to security reasons.

I've read on the documentation site that there's a CheckAuthentication() function to enable somewhere, but it's not clear where and how to do that.

I'd like to know:
- what file do i have to edit?
- how do i enable file browsing/uploading?
- how do i specify target folders for files, images, etc... like good old FCKEditor's Filemanager (QuickUploadPath and QuickUploadAbsolutePath)?

Thanks again, have a great day.

Regards,
Tony.
