sasl_server_new - Create a new server authentication object
int sasl_server_new(const char *service,

const char *user_realm,
const char *iplocalport,
const char *ipremoteport,
const sasl_callback_t *callbacks,
sasl_conn_t ** pconn);
sasl_server_new() creates a new SASL context. This context will be used for all SASL calls
for one connection. It handles both authentication and integrity/encyption layers after
service is the registered name of the service (usually the protocol name) using SASL (e.g.
serverFQDN is the fully qualified server domain name. NULL means use gethostname(). This
is useful for multi-homed servers.
user_realm is the domain of the user agent. This is usually not necessary (NULL is
iplocalport is the IP and port of the local side of the connection, or NULL. If iplocal-
port 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 iplo-
secflags are security flags (see below)
pconn is a pointer to the conection context allocated by the library. This structure will
be used for all future SASL calls for this connection.
Security flags that may be passed to sasl_server_new() include
Don't permit mechanisms susceptible to simple passive attack (e.g., PLAIN, LOGIN)
Protection from active (non-dictionary) attacks during authentication exchange.
Don't permit mechanisms susceptible to passive dictionary attack
Require forward secrecy between sessions. (breaking one won't help break next)
Require mechanisms which pass client credentials, and allow mechanisms which can
pass credentials to do so.
sasl_server_new() returns an integer which corresponds to one of the SASL error codes.
SASL_OK is the only one that indicates success. All others indicate errors and should
either be handled or the authentication session should be quit.
