Hi

I also encountered this issue and found out that Windows' GSSAPI
library checks if the target server can be trusted before delegating
tickets to it. If you trust the target system, tickets can be
forwarded to it and things work as expected. Note that ssh(1) on Linux
doesn't do this check i.o.w. using ssh(1)'s -K option just works.

To configure this:

"AD Users and Computers" > search the target host > properties >
Delegation tab > Trust...

-- 
Kind regards
