Is it possible to authenticate Windows clients against MIT Kerberos (no AD)?

This is possible using the built-in Microsoft Kerberos as well without adding software. There are a few threads from this list about how to do it.

Basically, you need to:
Use KSetup to configure the Windows machine with settings about your MIT realm.
Create a host principal on the MIT KDC and set the same machine password with ksetup to "Join" the MIT realm.
Use Ksetup to map MIT users to local SAM users 

Also remember that Windows does not support all enctypes, so your KDC will have to support at least one of:
AES-128 (Vista +)
AES-256 (Vista +)

Yes, of course it is. Just use the Kerberos client for Windows:

However, all this gets you is bare-bones Kerberos authentication; you  
still need to log in to Windows first. So, you might consider  
combining that with the pGina client...

... and the Kerberos plugin for it:

But, even if you get all that to work, your users will still need  
local accounts on all the Windows workstations before they can log in;  
local accounts are not created for them automatically, nor are they  
stored on the network.

If you don't like that idea, it seems that currently your only other  
options are either to buy a license for a M$ Windows server, or wait  
for Samba4:
