JAAS Kerberos login module

Java JAAS module is not necessarily used to obtain local credentials,
right? I tried a program using a different KDC on another realm and it
still works, the only thing I needed to do is just to specify the KDC
and realm of the destination.

Thx,

The appropriate place for this discussion is kerberos at mit.edu or the 
comp.protocols.kerberos
newsgroup.  The krbdev at mit.edu mailing list is meant to be used for 
discussion on the
development of the MIT Kerberos implementation.

I am redirecting replies to kerberos at mit.edu

As a hint: Java JAAS modules do not perform network authentication.  
They are used to obtain
local credentials which may or may not be used in the future input to 
the network authentication
protocol such as GSS-API.  Java provides its own implementation of 
GSS-API Kerberos 5 for use
in communicating with other GSS-API Kerberos 5 compatible clients and 
servers.
