sasl_server_new(3) Create a new server authentication object


#include <sasl/sasl.h>

int sasl_server_new(const char *service,
const char *serverFQDN,
const char *user_realm,
const char *iplocalport,
const char *ipremoteport,
const sasl_callback_t *callbacks,
unsigned flags,
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/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 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 default)

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 iplocalport)

flags are connection flags (see below)

pconn is a pointer to the connection context allocated by the library. This structure will be used for all future SASL calls for this connection.

Connection Flags

The protocol supports a server-last send
Force the use of a mechanism that supports an authorization id that is not the authentication id.


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.
