I have inherited an ifolder 2.1 system running on NW65SP6. Our Security Admin forgot his passphrase and his pc was recently wiped. He asked us to retrieve his passphrase but none of the current system admins knew the password. I followed TID10085581 to reset the security passphrase to something I know, however when I try to recover this user's passphrase I get:

Pass Phrase Recovery for User: username
Pass Phrase Pass phrase decrypt error

How can I get this user's data recovered?
