Can I automatically cache AD tickets into a file on windows?

[Mauro Cazzari]

Perfect! I'll give it a shot to see if it works in my case.
Thanks!

MIT KfW does include a utility "ms2mit.exe" that attempts to export kerberos credentials from the Windows LSA to a KfW credentials cache (which by default will be an API: cache but can be configured to be a FILE: cache).  However, those attempts will fail in some situations, such as when the user is a local administrator, on recent versions of Windows.  Some sites have run ms2mit during the login process to get that sort of behavior; however, in the KfW 4.1 series, the LSA: support is improved and it may be feasible to just use the LSA: cache directly.
