NAME
sasl_checkapop - Check an APOP challenge/response
SYNOPSIS
#include <sasl/sasl.h>
int sasl_checkapop(sasl_conn_t *conn,
const char *challenge,
unsigned challen,
const char *response,
unsigned resplen);
DESCRIPTION
sasl_checkapop() will check an APOP challenge/response. APOP is an optional POP3 (RFC 1939)
authentication command which uses a shared secret (password). The password is stored in the SASL secrets
database. For information on the SASL shared secrets database see the System Administrators Guide in the
doc/ directory of the SASL distribution.
If called with a NULL challenge, sasl_checkapop() will check to see if the APOP mechanism is enabled.
RETURN VALUE
sasl_checkapop returns an integer which corresponds to one of the following codes. SASL_OK indicates that
the authentication is complete. All other return codes indicate errors and should either be handled or
the authentication session should be quit. See sasl_errors(3) for meanings of return codes.
