Verifying a users password on AIX setup with LPA
Hello,
We're running AIX 6 & 7.
Previously we were using the old encryption techinique (DES/crypt)
I have a GUI application that has a verify button (the verify button is sort of a digital signature) - the user clicks it, enters his or her password and we then make a call to a C module, This grabs the hash value password from the shadow file.
We then grab the salt from the hashed value and make a to the crypt function, which returns an encrypted string that we compare to the shadow string to verify the user is valid.
We've now introduced LPA onto our server which has effectively broken our verification.
I've looked at the "authenticate" function provided by libc, however, I have been unable to make this work (doesnt seem to do anything).
The manpage for the crypt function seems to signify that you can use LPA, but again, I havent been able to make this work either. I believe I am passing in the correct salted value, but the string returned is always different so there's no way to match the hashed string with this one.
Would anyone know of an alternative way to verify a user on the system from within an application (without dropping them out to a commandline) ?
Thanks,
Chris

glutbuttonboxfunc
glutButtonBoxFunc(3GLUT) GLUT glutButtonBoxFunc(3GLUT)
NAME
glutButtonBoxFunc - sets the dial & button box button callback for the current window.
SYNTAX
#include <GLUT/glut.h>
void glutButtonBoxFunc(void (*func)(int button, int state));
ARGUMENTS
func The new button box callback function.
DESCRIPTION
glutButtonBoxFunc sets the dial & button box button callback for the current window. The dial & button box button callback for a window is
called when the window has dial & button box input focus (normally, when the mouse is in the window) and the user generates dial & button
box button presses. The button parameter will be the button number (starting at one). The number of available dial & button box buttons can
be determined with glutDeviceGet(GLUT_NUM_BUTTON_BOX_BUTTONS). The state is either GLUT_UP or GLUT_DOWN indicating whether the callback was
due to a release or press respectively.
Registering a dial & button box button callback when a dial & button box device is not available is ineffectual and not an error. In this
case, no dial & button box button callbacks will be generated.
Passing NULL to glutButtonBoxFunc disables the generation of dial & button box button callbacks. When a new window is created, no dial &
button box button callback is initially registered.
