VNC Authentication Failed

[Clarke O. Mazza]

I am a fairly new user of VNC 3.3.4.    I can get a connection just fine,
until I set the <AllowProperties> and <AllowShutdown> to zero.  I then get
an error message on the password of "VNC Authentication Failed".  When I
return the <AllowProperties> and <AllowShutdown> back to "1", then the log
on process works OK.  I do want to disallow these two attributes.  Any
suggestions?
