NAME¶

sasl_callbacks - Cyrus SASL documentation

SYNOPSIS¶

#include <sasl/sasl.h>

DESCRIPTION¶

sasl_callbacks are used when the application needs some information from the application. Common reasons are getting for getting usernames and passwords. A client MUST specify what callbacks they support in the sasl_client_init(3)/sasl_server_init(3) or sasl_client_new(3)/sasl_server_new(3) calls. If an authentication mechanism needs a callback that the application does not state it supports it cannot be used.

If a callback has an id parameter that should be checked to make sure you are giving the appropriate value.

If an application is using the client side of the library functions to handle the callbacks are not necessary. Instead the application may deal with callbacks via SASL_INTERACT’s. See sasl_client_start(3)/sasl_client_step(3) for more information.

RETURN VALUE¶

SASL callback functions should return SASL return codes. See sasl_errors(3) for a complete list. SASL_OK typically indicates success.
