Key version in .NET

[John Brezak]

In RC1 of .NET server, you will see small numbers based on the password
generation number for key version numbers of accounts. We made this
change due to a bug in other Kerberos implementations that only allowed
key version numbers < 255.

The ktpass.exe in RC1 will set the kvno in the keytab correctly.

The Beta release had key version numbers based on the last password
change time - minus the account creation time. You can see the kvno by
examining the "msDS-KeyVersionNumber" attribute on the account object.

FYI- Trusts are not key versioned in .NET server. This will be addressed
in a future version of Windows.

I thought ActiveDirectory used the same kvno all the time...
