pdf is kinda standard, did you try the document in another viewer or even other OS?
the password is hashed in the database i believe, possibly you could try to put a cleartext in the field for the password at the user you need… it worked in the old ADNM environment possibly here too
ofcourse this would mean that you need write access in the database itself (either your windows account or the sa account needs to have that right)
there has never been a password reset in ADNM. In ADNM the way i mention it, was the way to reset the password.
After login with the new plaintext password, it gets hashed or at least encrypted somehow and written back in the database.
ofcourse logging into the database itself is not the good way to reset, but as far as i know at this moment, there is no other way and i also do not know if in this version this trick works…
