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 secflags,
		       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 authentica-
       tion 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.

       secflags are security 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.

       Security Flags

       Security flags that may be passed to sasl_server_new() include

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

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

       SASL_SEC_NODICTIONARY
	       Don't permit mechanisms susceptible to passive dictionary attack

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

       SASL_SEC_NOANONYMOUS
	       Don't permit mechanisms that allow anonymous login

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

       SASL_SEC_MAXIMUM
	       All of the above.

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
