sasl_client_new() creates a new SASL context. This context will be used for all SASL calls for one connection. It handles both authentication and integrity/encryption layers after authentication.
service is the registered name of the service (usually the protocol name) using SASL (e.g. "imap").
serverFQDN is the fully qualified domain name of the server (e.g. "serverhost.cmu.edu").
iplocalport is the IP and port of the local side of the connection, or NULL. If
iplocalport is NULL it will disable mechanisms that require IP address
information. This strings must be in one of the following formats:
"a.b.c.d;port" (IPv4), "e:f:g:h:i:j:k:l;port" (IPv6),
or "e:f:g:h:i:j:a.b.c.d;port" (IPv6)
ipremoteport is the IP and port of the remote side of the connection, or NULL (see
prompt_supp is a list of client interactions supported that is unique to this connection. If this parameter is NULL the global callbacks (specified in sasl_client_init) will be used. See sasl_callback for more information.
flags are connection flags (see below)
pconn is the connection context allocated by the library. This structure will be used for all future SASL calls for this connection.
Flags that may be passed to
The protocol supports a server-last send
Force the use of a mechanism that supports an authorization id that is
not the authentication id.
