NAMEsasl_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);
DESCRIPTIONsasl_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 usu-
ally 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 dis-
able 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 pas-
sive 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. (break-
ing 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 VALUEsasl_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.
