Ms-Logon input password length is too small?

Hi

It appears that the character limit allowed by MS-Logon is really restricted.
Testing with a ~35 character password or so, it seems that towards the last 2-3 characters, that I hear the sound windows plays when you fill a text field to the max, and unable to login with that account

I think that Windows supports 127 character passwords

I tested with the latest version of uVNC

Thanks

ms-logon passwd is hardcoded to 32 chars
Changing this breaks the server/client protocol, this is not something we can change easy without breaking backward compatibility.
Possible our mslogon dll's also use 32 chars..

Longer passwords are supported with the encryption plugins, but then it's a plugin password and not a ms passwd.

XP/windows 2003 i MS password boxes are limit to 32, you can only enter a 32 char passwd
AD 127 chars, but can't be changed as passwd boxes only accept 32

2008/WIndows 10 with local account 127 chars
windows 10 with ms account 16 chars

UltraVNC
