Hi. I am new to this list and to PAM so I hope that you all will be nice to
me :-)
The company that I am working for have diced that over program will use PAM
as an authentication.
The program is used under Linux, Sun and Digital.
I have made a small program to test it. It looks like this.
#include <security/pam_appl.h>
#include <security/pam_misc.h>
#include <stdio.h>
static struct pam_conv conv = {
misc_conv,
NULL
};
int main(int argc, char *argv[])
{
pam_handle_t *pamh=NULL;
int retval;
const char *user="guest";
retval = pam_start("check_user", user, &conv, &pamh);
if(argc == 2) {
user = argv[1];
}
if(argc < 2) {
fprintf(stderr, "Usage: check_user [username]\n");
exit(1);
}
if (retval == PAM_SUCCESS)
retval=pam_set_item(pamh,PAM_USER,user);
if (retval == PAM_SUCCESS)
retval = pam_authenticate(pamh, 0); /* is user really user? */
if (retval == PAM_SUCCESS)
retval = pam_acct_mgmt(pamh, 0); /* permitted access? */
/* This is where we have been authorized or not. */
if (retval == PAM_SUCCESS) {
fprintf(stdout, "Authenticated\n");
} else {
fprintf(stdout, "Not Authenticated\n");
}
if (pam_end(pamh,retval) != PAM_SUCCESS) { /* close Linux-PAM */
pamh = NULL;
fprintf(stderr, "check_user: failed to release authenticator\n");
exit(1);
}
return ( retval == PAM_SUCCESS ? 0:1 ); /* indicate success */
}
Now to my problem.
1) The program I am manage is using a webpage for the user to login
to. So I can?t use misc_conv an as I understand is that misc_conv and
pam_misc.h is Linux specified. So how should I write the program so that
misc_conv is not used so that I can send in the password before
pam_authenticate. I like to do something like this
retval=pam_set_item(pamh,PAM_USER,user); but for password.
2) This should also work on Solaris and in the further Digital.
What I would like is a small example code. So if you known some program or
webpage that have this please show me the way.
Sorry for my English.
