find PAM library version

[Sudarshan Soma <sudarshan12s gmail com>]

Hi All,
Can anyone please tell me if i can determine the libpam version with
pam_unix module. I have pam_unix.so, but i dont know with which libpam
its linked with. It just shows me libpam.so in ldd.

Please let me know if i can determine the exact version such as
libbpam.so.0.81.6(which is available from Linux-PAM-0.99.7.1.tar.gz
(http://www.kernel.org/pub/linux/libs/pam/pre/library/)

Please correct me , if iam missed something.

Thanks and Regards,
Pavan
