I am building a collection of some PDF and Word documents for the
user of intranet site of an organization .

in the course of building collection of PDF and word documents i
feel need of some technique to restict the user [reader] to print
the PDF documents or to restict to download of the documents. I
want to give the read access of PDF documents to the
readers[users] rather than downloading it.

Does greenstone provide some feature that prevent user to download
the documents. or is there any facility it have to provide
authentication to the user.
