sasl_server_start

sasl_server_start(3SASL)		      Simple Authentication Security Layer Library Functions			  sasl_server_start(3SASL)

NAME

       sasl_server_start - create a new server authentication object

SYNOPSIS

       cc [ flag ... ] file ... -lsasl	 [ library ... ]
       #include <sasl/sasl.h>

       int sasl_server_start(sasl_conn_t *conn, const char  *mech, const char  *clientin, unsigned *clientinlen, const char  **serverout, unsigned
       *serveroutlen);

DESCRIPTION

       The sasl_server_start() interface begins the authentication with the mechanism specified by the mech parameter.	sasl_server_start()  fails
       if the mechanism is not supported.

PARAMETERS

       conn	       The SASL context for this connection.

       mech	       The mechanism name that the client requested.

       clientin        The initial response from the client. The value of clientin is NULL if the protocol lacks support for the client-send-first
		       or if the other end did not have an initial send.  No initial client send is distinct  from  an	initial  send  of  a  null
		       string. The protocol must account for this difference.

       clientinlen     The length of the initial response.

       serverout       Created	by  the  plugin library. The value of serverout is the initial server response to send to the client. serverout is
		       allocated or freed by the library. It is the job of the client to send it over the network to the server. Protocol specific
		       encoding, for example base64 encoding, must be done by the server.

       serveroutlen    The length of the initial server challenge.

RETURN VALUES

       sasl_server_start() returns an integer that corresponds to a SASL error code.

ERRORS

       SASL_OK	       Authentication completed successfully.

       SASL_CONTINUE   The call to sasl_server_start() was successful, and more steps are needed in the authentication.

       All  other  error  codes  indicate  an  error  situation  that  must  be  handled,  or  the  authentication  session  should  be  quit. See
       sasl_errors(3SASL) for information on SASL error codes.
