[LIP] PAM Error on HP 11i change password works only for root

I write a sample program to test PAM functionality. basically pam_chauthtok.

It is prefectly working in most of the Unix flavours bit not in HP UX 11i.

My program


#define DEBUG
#include <security/pam_appl.h>
#include <stdio.h>
#include <pwd.h>
#include <stdlib.h>
#include <string.h>
/*
 * PAM call back function to read the password values
 */

extern int convert(int num_msg,struct pam_message **msg,struct
pam_response **resp,void *appdata_ptr)
{
    // Initialize PAM response object and set password
    struct pam_response *temp;
    temp = (struct pam_response *)calloc(num_msg,sizeof(struct pam_response));
    temp[0].resp_retcode = 0;
    temp[0].resp = strdup((const char*)appdata_ptr);
    *resp = temp;
    return PAM_SUCCESS;
}
static struct pam_conv conv = {convert,NULL};
/*
 * Function used to change the password of a user
 */
int changePasswd(char *user,char *pass)
{
    pam_handle_t *pamh=NULL;
    int retval;
    struct pam_response *pp=NULL;
    conv.appdata_ptr = pass;
    // initialize PAM
    retval = pam_start("fisclsnr", user, &conv, &pamh);
    if (retval == PAM_SUCCESS)
    {	
	// Change password (auth tocken)
	retval = pam_chauthtok(pamh, PAM_SILENT);
    }
    if (retval != PAM_SUCCESS)
    {
	return -1;
    }
    // End PAM Session
    if (pam_end(pamh,retval) != PAM_SUCCESS)
    {
	pamh = NULL;
	return -1;
    }
    return 0;
}
int main()
{
	int res = changePasswd("india","ClassObject123");
	printf( "Res = %d", res);
	return 0;
}


If I am trying to change the password of a normal user it doesnot work.
But change password of root user works fine. Anyone have any Idea
