PARAMETERS:
client_properties: table
client properties
mechanism: shortstr
selected security mechanism
A single security mechanisms selected by the client,
which must be one of those specified by the server.
RULE:
The client SHOULD authenticate using the highest-
level security profile it can handle from the list
provided by the server.
RULE:
The mechanism field MUST contain one of the
security mechanisms proposed by the server in the
Start method. If it doesn't, the server MUST close
the socket.
response: longstr
security response data
A block of opaque data passed to the security
mechanism. The contents of this data are defined by
the SASL security mechanism. For the PLAIN security
mechanism this is defined as a field table holding two
fields, LOGIN and PASSWORD.
locale: shortstr
selected message locale
A single message local selected by the client, which
must be one of those specified by the server.
