NAME
sasl_server_new - Create a new server authentication object

SYNOPSIS
#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 secflags,
			 sasl_conn_t ** pconn);

DESCRIPTION
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 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)

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

Security flags that may be passed to sasl_server_new() include

NOPLAINTEXT
    Don't permit mechanisms susceptible to simple passive attack (e.g., PLAIN, LOGIN)

NOACTIVE
    Protection from active (non-dictionary) attacks during authentication exchange. Authenticates server.

NODICTIONARY
    Don't permit mechanisms susceptible to passive dictionary attack

FORWARD_SECURITY
    Require forward secrecy between sessions. (breaking one won't help break next)

PASS_CREDENTIALS
    Require mechanisms which pass client credentials, and allow mechanisms which can pass credentials to do so.

RETURN VALUE
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.
