SECURITY HELP! R6 Reader names not workig via Browser

I am testing a testing a migration from R5 to R6.01 for a customer and I am testing an existing application that uses Reader Names in R5 and it works great for the Notes and browser clients. When I do a New Copy of the database to the R6.01 test server the Readers names fields in the documents works great for the Notes client but they are being “ignored” via a browser. i.e. Any user with reader access is seeing all the documents instead of only the ones without a reader field. This is obviously a bad security problem that needs to be resolved. When I copy the same database to and R6.0 server in our company’s environment the readers works fine via the browser.Any option that needs to be set in 6.0 or 6.01?

Any thoughts?

Any help is appreciated… Thanks.
