libmemcached allows you to plug in your own callbacks function used by libsasl to perform SASL authentication.

Please note that SASL requires the memcached binary protocol, and you have to specify the callbacks before you connect to the server.

memcached_set_sasl_auth_data() is a helper function defining the basic functionality for you, but it will store the username and password in memory. If you choose to use this method you have to call memcached_destroy_sasl_auth_data() before calling memcached_free() to avoid a memory leak. You should NOT call memcached_destroy_sasl_auth_data() if you specify your own callback function with memcached_set_sasl_callbacks().

memcached_get_sasl_callbacks() returns the callbacks currently used by this memcached handle. memcached_set_sasl_auth_data() returns MEMCACHED_SUCCESS upon success.
