* instruct the server to await separate privilege-acquisition commands.
* "user": The std::string name of the user to authenticate.
* "db": The database target of the auth command, which identifies the location
* of the credential information for the user. May be "$external" if credential
* information is stored outside of the mongo cluster.
* "pwd": The password.
* "serviceName": The GSSAPI service name to use. Defaults to "mongodb".
* "serviceHostname": The GSSAPI hostname to use. Defaults to the name of the remote host.
*
* Other fields in saslParameters are silently ignored.
