Without the owner password, you do not have permission to insert, delete, or rotate pages of the document.
Why has this not been addressed properly by anyone at APPLE? This is so annoying. I created the document and it was digitally signed by my clients. there is no password. I am the only one with permissions on this computer so why is this asking for a password when I open the doc in PREVIEW? I entered my password that unlocks my Mac but that was useless and then it wouldn't let me cancel or unlock. IN fact, it just wouldn't do anything. I couldn't restart because that window wouldn't cancel and I cannot shut the computer down because that window remains open asking me for a password, or cancel or unlock, none of which works. GRRRR.
