PAM Python Unix authentication without root privilege

Question

I have a python script with PAM authentication, executes and prints success if it is executed with root where as if I execute it with non root privilege I am getting the below error

python: pam_unix(system-auth:auth): authentication failure;

Is there any possibility that I can run it with non root privilege please help me out.

FYI -

I am using the python script from https://code.google.com/p/web2py/source/browse/gluon/contrib/pam.py

Thanks

Please follow me. Enter following command in console. $su root $chmod 7777 ./script $chown root root ./script

later excute setuid(root), setgid(root) function in script file.
