disabling Kerberos V4 in leash32

[Christian]

Hello,

I got a problem here with Kerberos for Windows 2.1.2..
I need to authenticate Windows (NT & 2000) Clients against KDC.

It would be very cool, when it's possible to disable the Kerberos V4
authentication-try, because we only got an Kerberos V5 Service
running and don't want a "524-Service".

Is that possible? (command-line and GUI)

Thanks in advance.
