Kerberos v5 support

The sites I login to require kerberos v5 ticket forwarding. Would it be possible to implement that? FileZilla already supports Kerberos ticket forwarding, if you wanted something to refer to. It's open-source and can be found here:

https://filezilla-project.org/

I'll look at that.

Even if you decide not to do it, thank you for at least looking.
