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