Prototype for the connection creation callback
Prototype for the connection creation callbackThis calls sasl_client_new or sasl_server_new with whatever callback information is desired, and, on success, makes a call to sasl_setprop to set the desired security properties with SASL_SEC_PROPS.
Another reason to supply this callback, is it allows you to squirrel away the connection pointer to later call sasl_getprop.
