Sendauth from windows(client) to linux(server)

[Arturo Sandrigo]

Hi,
I'm writing a client server application and i need to develop a windows
client.
Actually i developed the server and a basic linux client to test it.
all it's working ok and the interaction between server and client is
correct.
Now i'm trying to port the client to windows, but i have problem with
sendauth.
Even if i can get the TGT for my client's pincipal and the TGS for my
service when
i use sendauth i got the -1765328178 error,on the linux client everything
works ok
so i wonder ho i can fix this problem, can anyone point me on the right
direction ?
Thanks
