sasl_server_step - Perform a step in the authentication negotiation

Synopsis

#include <sasl/sasl.h>

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

Description

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

sasl_server_step() performs a step in the authentication negotiation. It returns SASL_OK if the whole negotiation is successful and SASL_CONTINUE if this step is ok but at least one more step is needed.

Parameters

  • conn – is the SASL connection context

  • clientin – is the data given by the client (decoded if the protocol encodes requests sent over the wire)

  • clientinlen – is the length of clientin

  • serverout – set by the library and should be sent to the client.

  • serveroutlen – length of serverout.

Return Value

SASL callback functions should return SASL return codes. See sasl.h for a complete list. SASL_CONTINUE indicates success and that there are more steps needed in the authentication. SASL_OK indicates that the authentication is complete.

Other return codes indicate errors and should either be handled or the authentication session should be quit.
