sasl_server_start(10 July 2001) 										   sasl_server_start(10 July 2001)

NAME

       sasl_server_start - Begin an authentication negotiation

SYNOPSIS

       #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

       sasl_server_start() begins the authentication with the mechanism specified with mech. This fails if the mechanism is not supported. SASL_OK
       is returned if the authentication is complete and the user is authenticated. SASL_CONTINUE is returned if  one  or  more  steps	are  still
       required in the authentication. All other return values indicate failure.

       conn is the SASL context for this connection

       mech is the mechanism name that the client requested

       clientin  is the client initial response, NULL if the protocol lacks support for client-send-first or if the other end did not have an ini-
       tial send.  Note that no initial client send is distinct from an initial send of a null string, and the protocol MUST account for this dif-
       ference.

       clientinlen is the length of initial response

       serverout is created by the plugin library. It is the initial server response to send to the client. This is allocated/freed by the library
       and it is the job of the client to send it over the network to the server. Also protocol specific encoding (such as base64  encoding)  must
       needs to be done by the server.

       serveroutlen is set to the length of initial server challenge

RETURN VALUE

       sasl_server_start  returns  an  integer which corresponds to one of the SASL errorcodes. SASL_OK indicates that authentication is completed
       successfully. SASL_CONTINUE indicates success and that there are more steps needed in the authentication. All other return  codes  indicate
       errors and should either be handled or the authentication session should be quit.
