Description peake 2004-10-16 06:09:56 UTC
Please describe the problem:
I wanted to set my password, but after 8 chars entered there's no more *
appearing, like if the password has a maximum of 8 chars

Steps to reproduce:
1. Check on 'Allow other users to view your desktop'
2. Check 'Required the user to enter this password'
3. Enter something with more than 8 characters


Actual results:
I can't enter more than 8 characters

Expected results:
That my password is fully taken

Does this happen every time?
Yes

Other information:
I don't know if it's related but if I enter something like 12345678 as my
password and I connect to my desktop with 'vncviewer 127.0.0.1:0', when I'm
asked to enter the password I enter 12345678<some other random char> , the
connection is made even if the password is obliviously wrong.

Standard problem with VNC:

  http://www.uk.research.att.com/archive/vnc/faq.html#q55

I think the FAQ is wrong, though. The problem stems from the fact that VNC
authentication is a simple challenge-response scheme where you're password is
used as a key to encrypt a 16 byte challenge from the server. DES's key length
is 56 bits - i.e. 7 characters.
