Hi,
I'm trying to modify the latest
version of gdm to make use of the cuecat barcode scanner as an authentication
mechanism. There is a PAM module that will give users the option of scanning a
barcode through with the cuecat instead of using a password, but I want to make
it so that users have the option of simply swiping their barcode and
be identified and logged in - without a username or password, essentially
bypassing the PAM authentication system altogether. I'm having trouble getting
the system to log in a user as I was planning. I've tried modifying the
gdm_verify_user function in verify-pam.c and simply inserting
return "bob";
within the loop, so that the system simply logs in
bob, but that doesn't work. I also tried almost copying the
gdm_verify_setup_user function into the beginning of gdm_verify_user and
mimicking the way it starts a pam session and does all kinds of administrative
stuff without actually authenticating any password, but that doesn't work
either. I also tried going to slave.c where gdm_verify_user is called and
calling the latter function so that it goes right into an X session without even
waiting:
gdm_verify_setup_user("bob",d->name);
but that had no effect at all. Is there something
I'm missing here? Obviously, my X/gdm/PAM programming skills are sorely
lacking... I would greatly appreciate any help here...
