Testing PAM modules and PAM-aware applications in the Matrix
Jakub Hrozek and I are proud to announce the first release of pam_wrapper. This tool allows you to either simplify testing PAM modules or your application using PAM to authenticate users. PAM (Pluggable Authentication Modules) is a layer of abstraction on top of Unix authentication.
For testing PAM-aware applications we have written a simple PAM module called pam_matrix. If you plan to test a PAM module you can use the pamtest library we have implemented. It simplifies testing of modules. You can combine it with the cmocka unit testing framework or you can use the provided Python bindings to write tests for your module in Python.
Jakub and I have written an article for LWN.net to provide more details how to use it. You can find it here.
Now start testing your PAM module or application!
