NAME

       sasl_server_start - Cyrus SASL documentation

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

       int sasl_server_start(sasl_conn_t * conn,

       const char * mech,

       const char * clientin,

       unsigned * clientinlen,

       const char ** serverout,

       unsigned * serveroutlen);
              sasl_server_start()  begins  the  authentication  with the mechanism specified with
              mech. This fails if the mechanism is  not  supported.

              Parameters

                     • conn – is the SASL connection context

                     • 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
                       initial send.  Note that no  initial  client  send  is  distinct  from  an
                       initial   send  of  a  null string, and the protocol MUST account for this
                       difference.

                     • 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  callback  functions should return SASL return codes. See sasl.h for a complete list.
       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 errors  and  should  be  handled  or  the  authentication
       session should be quit.
