Please read chapter 12 of "iText in Action - Second Edition".
A PDF can be created using two passwords:
- a user password
- an owner password
If a user password was provided, the user will be prompted for a 
password. If no user password was provided, the user can view the PDF, 
but some functions may be restricted. For instance: you can encrypt a 
PDF using an owner password to prevent people from printing the 
document. Viewers usually check the permissions, but iText doesn't allow 
you to create a PdfReader object if there was an owner password and you 
don't provide that password.
Hope this explains what's happening.
