Hello all,
I am trying to develop a simple window with one entry (pin code) to
authenticate an smartcard on GDM 2.24. I am studying gdm code for a few
days trying to find a simple way to do that. I could have some ideas,
but I got lost on gobject code and IPC mechanism used. Looking at
GdmGreeterLoginWindow object I saw that it register some signals and
when the password is captured a "query-answer" signal is emited. But I
could not understand how this signal get captured by gdm-slave process
and how this information is sent (encapsulated). Could anyone explain
how it works?
To avoid modifying gdm source code and making things easier, I wrote a
simple binary that reads from dbus the information of
insertion/removing the smartcard and show/hide the PIN code window
entry. Now what I just need is to send this text_entry to gdm daemon
(and obviously, PAM - pam_pkcs11). Any ideas on how can I do that?
ps: this program is started by gdm autostart
(/usr/share/gdm/autostart/LoginWindow/program.desktop). It is working
on the sense of appearing and disappearing the window, but not the
"talk mechanism" with gdm to verify the pin code.
Thanks in advance,
Global
