<b>NOTE:</b> It is not recommended to use a SASL mechanism of
PLAIN with SASL_PLAINTEXT, as it would transmit
the username and password unencrypted.
+ <b>NOTE:</b> The Kerberos Service Name is not required for SASL
mechanism of PLAIN. However, processor warns saying this attribute has to be
filled with non empty string. You can choose to fill any random string. I
prefer "null".
