The
OncRpcClientAuth
class is the base class for handling
all protocol issues of ONC/RPC authentication on the client side. As it
stands, it does not do very much with the exception of defining the contract
for the behaviour of derived classes with respect to protocol handling
issues.
Authentication on the client side can be done as follows: just create an authentication object and hand it over to the ONC/RPC client object.
OncRpcClientAuth auth = new OncRpcClientAuthUnix( "marvin@ford.prefect", 42, 1001, new int[0]); client.setAuth(auth);The
authentication AUTH_UNIX
will
handle shorthand credentials (of type AUTH_SHORT
transparently).
If you do not set any authentication object after creating an ONC/RPC client
object, AUTH_NONE
is used automatically.- Version:
