Hi Victor,

  That just means that the server requires more information from the client. 
This could happen if mutual authentication is required or the dataset is too 
large and had to be split. If you run it in squid the client would send new 
data until the server says the exchange is complete ( I have not programmed 
this into the simple test tool).

Now as I run the test authenticator, what's the
"INFO: continuation needed"
message from the squid Kerberos helper? How do I interperet it? Is it
success or fail?

See output below:
