GSSAPI delegate

Can the option be added to allow GSSAPI delegation of credentials when GSSAPI authentication is selected ?

Right now, WinSCP doesn't actually delegate the credentials to the server, which means it does not have a ticket on the server side for the user. This breaks things like AFS, which need the ticket to create a token for user authentication.

OpenSSH, when patched for GSSAPI/Kerberos, allows this, as does the patched versions of PuTTY floating around.

I have forwarded your request to an author of Kerberos implementation in WinSCP.

After consulting with author of Kerberos implementation, it seems that you ask for feature that is available in Putty under name Allow Kerberos 5 ticket forwarding in GSSAPI/SSPI. Is this what you ask for?
