Windows: Obtain Kerberos TGT from another principal

Question

I'm looking for a way to obtain a tgt (ticket granting ticket) from a second kerberos principal. In my job I work with a regular PC (member of AD) from our university's it departement but I also manage a lab with it's own AD. To make the daily use much easier I consider it a rather nice option to have another tgt on my Windows 7 machine. On an *nix I'd use kinit - but on Windows...? Thank you for your support

Answer 1

If you start a new shell (cmd.exe) under the alternate domain account using runas.exe, that will have its own security context and credential cache for the corresponding Kerberos principal, which programs you start from it will inherit.
