NAME
sasl_client_new - Create a new client authentication object

SYNOPSIS
#include <sasl/sasl.h>

int sasl_client_new(const char *service,
			 const char *serverFQDN,
			 const char *iplocalport,
			 const char *ipremoteport,
			 const sasl_callback_t *prompt_supp,
			 unsigned flags,
			 sasl_conn_t ** pconn);

DESCRIPTION
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/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 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 iplocalport)

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 conection context allocated by the library. This structure will be used for all future SASL calls for this connection.

Connection Flags

Flags that may be passed to sasl_server_new() include

SASL_SUCCESS_DATA
    The protocol supports a server-last send

SASL_NEED_PROXY
    Force the use of a mechanism that supports an authorization id that is not the authentication id.

RETURN VALUE
sasl_client_new returns an integer which corresponds to one of the following 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.

ERRORS

SASL_OK
    Success

SASL_BADPARAM
    Error in config file or passed parameters

SASL_NOMECH
    No mechanism meets requested properties

SASL_NOMEM
    Not enough memory to complete operation
