librapam

A simple library to use Linux-pam for user login and change password. If you want to change the password using the library, you should run your program as root at this phase of the project.

For using the library, you should copy the librapam config file, that exists in etc/pam.d/librapam, into your system at /etc/pam.d/librapam. Don't change the file name, because the file name is hardcoded in the library.

build

First of all, please clone the project.

git clone https://github.com/khozaei/librapam

Then run these sequences of commands to build the project. You need libpam and cmake to build.

cd librapam
mkdir build
cd build
cmake ..
make

usage example

The library is so simple:

#include "librapam.h"

#include <stdio.h>

int
main (int argc, char *argv[])
{
  int retval;

  retval = librapam_check_user("amin", "password_example");
  if (retval == LIBRA_SUCCESS)
    printf("login successful!\n");
  else
    printf("login failed!\n");

  retval = librapam_change_password("root", "password_example", "new_password");
  if (retval == LIBRA_SUCCESS)
    printf("the user password changed successfully\n");
  else
    printf("changing password was not successful\n");
  return 0;
}
