The authentication works. Only the prompting is a problem. ...
Have a look at doc/programming.html#callbacks_interactions within the cyrus
sasl source.
Thanks for the hint.
Can you provide an example which includes callbacks that is
not working as expected?
No I could not.
For reference I came up with the following:
#include <stdlib.h>
#include <string.h>
#include <stdio.h>
#include <cyrus/imclient.h>
static int getsecret_func(sasl_conn_t *conn,
void *context __attribute__((unused)),
int id,
sasl_secret_t **psecret);
static struct imclient *imclient;
static int getauthname_func(void *context,
int id,
const char **result,
unsigned *len);
void fatal(const char *s, int code)
{
fprintf(stderr, "Fatal error: %s\n", s);
}
/* callbacks we support. This is a global variable at the
top of the program */
static sasl_callback_t callbacks[] = {
{
SASL_CB_GETREALM, NULL, NULL/* we'll just use an interaction if this
comes up */
}, {
SASL_CB_USER, NULL, NULL /* we'll just use an interaction if
this comes up */
}, {
SASL_CB_AUTHNAME, &getauthname_func, NULL /*A mechanism should call
getauthname_func if it
needs the authentication name */
},{
SASL_CB_PASS, &getsecret_func, NULL /* Call getsecret_func if
need secret */
}, {
SASL_CB_LIST_END, NULL, NULL
}
};
static int getsecret_func(sasl_conn_t *conn,
void *context __attribute__((unused)),
int id,
sasl_secret_t **psecret)
{
*psecret = malloc(sizeof(sasl_secret_t)+7);
char * secret = "cyrus\0";
*psecret = malloc(sizeof(sasl_secret_t*)+strlen(secret)+1);
static sasl_secret_t *x;
x = (sasl_secret_t *) realloc(x, sizeof(sasl_secret_t) +
strlen(secret));
memcpy(x->data,secret,sizeof(sasl_secret_t)+strlen(secret)+1);
x->len=strlen(secret);
*psecret = x;
return SASL_OK;
}
static int getauthname_func(void *context,
int id,
const char **result,
unsigned *len)
{
if (id!=SASL_CB_AUTHNAME) return SASL_FAIL;
char *authname = "cyrus\0";
*result = malloc(sizeof(char)*strlen(authname)+1);
*result = authname;
unsigned length =strlen(authname); ;
len=&length;
return SASL_OK;
}
char server[] = "localhost" ;
char port[] = "imap";
char mech[] ="CRAM-MD5";
char service[] = "imap";
int main() {
if(imclient_connect(&imclient, server, port,callbacks)) {
fprintf(stderr,
"error: Couldn't connect to %s %s\n",
server, port);
}
if(imclient_authenticate(imclient, mech,service,NULL, 0,256)) {
fprintf(stderr,
"error: Authentication failed");
}
return 0;
}
