Problem

Restrictions designated in a PDF document aren't honored when the document is opened using Adobe Reader 7.

Solution

This problem appears to unique to Adobe Reader 7. Specifically, restrictions are ignored when one of the following situations exists:

  • You assign a User password but not a Master password.
  • You assign both a User password and Master password, but both password are the same.

When assigning restrictions to a PDF document, create unique passwords both for the Master password and User password.
