-----------------------------------

> Currently, during SASL negotiation stage between ipc Client and Server, The server sends only a single serviceId (curresponding to a single principal) to the client. This is the principal the the server process is logged in as during startup.
> It is possible that in a multi-homed network, the server might be associated with more than one principal, and thus severs must provide the clients all possible principals it can use to connect to.
