linux login source code
Do you know where I can find the source code of login module for linux. Not gdm, just the login.
I am trying to develop a new authendication via signatures. Which is that the user provides some kinda of signature (such as finger prints or iris picture) and the login will take the signature and match with the user database. However, I can just hit enter at the login prompt because login will just return without even checking with PAM. So far I only created the pam module and I need to somehow modify login so it won't just return without checking with PAM. So if you know the solutions, please let me know.
