Install and usage of PAM Preprofile module v1.0

We have written a PAM module for Corunix to force script execution at authentication time. The module can be downloaded from here.

This module ensures that some program or script is run each time a user logs into the computer. Now, it isn't necessary to rely on a particular shell to exec the user's .profile, .bash_profile, .bashrc or similar.

Such functionality can be used to create links from the user's home directory to some location, or other needs.

The module was made as a modification of the example module "pam_permit".

Install and usage

To install this module you must compile and copy it into a known location, such as /lib/security

Next, edit /etc/pam.d/X, being X the PAM service you want the module to run at (eg: su, gdm...). Add the following line at the end of the file:

session required pam_preprofile.so my_program param1 ... paramN

When my_program is called, it will receive param1 ... paramN, plus a paramN+1 being the username that has just been authenticated. For example:

----

session required pam_preprofile.so /tmp/myprogram.sh /usr/doc

----

#!/bin/sh

# This is /tmp/myprogram.sh

echo "Hello $2. Please, read the docs at $1."

----

NOTE: This module was written and tested only on Debian 3.0 (Woody) under PowerPC architecture.
