Detailed Description

An AuthProvider creates Thrift transports that are set up to authenticate themselves using a protocol such as Kerberos or PLAIN/SASL. Both server and client transports are provided by this class, using slightly different mechanisms (servers use a factory, clients wrap a pre-provided transport)
