A PAM HTTP BasicAuth module built using pam-rs
You need some libraries before you build like libpam and libssl.
If you're going to build on Ubuntu, just run this:
sudo apt-get install -y build-essential libpam0g-dev libpam0g libssl-dev
Just use cargo build.
You need to move the build product to a folder where PAM is looking for modules.
If you're using Ubuntu you can move libpam_http.so to /lib/security.
After doing so you need to make sure it has proper permissions: sudo chmod 755 /lib/security/libpam_http.so.
Then you can place a configuration file in /etc/pam.d/. It can look something like this:
auth sufficient libpam_http.so url=https://theserver.example.com/someendpoint
account sufficient libpam_http.so
Make sure the endpoint you're specifying can receive GET requests and supports HTTP Basic Authentication. If the user is authenticated successfully it should return HTTP 200.
