the pam module are generally kept in /etc/pam.d or /etc/pam.conf
and the program that we want for use will kept in /bin , /sbin or /usr/bin
, /usr/sbin so the diagram should be like application----->PAM api----->PAM module--->Back end..
and if any one want to use the PAm in your application will find the relevant header pam_modules.h in the /usr/include/security



so may one help me to do above thing that i have post at first
1st step :
login---->pam module---->store in file

2nd step:
when i want to lig in the pam module cheak the previous login name and password then permit ..
