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);
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.
The SASL context for this connection.
The mechanism name that the client requested.
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.
The length of the initial response.
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.
The length of the initial server challenge.
sasl_server_start() returns an integer that corresponds to a SASL error code.
Authentication completed successfully.
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.
