PAM authentication plugin for StackStorm

PAM authentication backend allows users to authenticate against the PAM (Pluggable Authentication Modules) on the system where st2auth service is running.

Requirements

Ubuntu:

sudo apt-get -y install libpam0g

RHEL/CentOS:

sudo yum -y install pam-devel

Installation

Install this into the ST2 virtualenv with:

sudo /opt/stackstorm/st2/bin/pip install git+https://github.com/StackStorm/st2-auth-backend-pam.git@master#egg=st2_auth_backend_pam

Edit the file: /lib/systemd/system/st2auth.service. Modify it so that the stauth service runs as root.

Configuration Options

Configuration Example

Please refer to the authentication section in the StackStorm documentation for basic setup concept. The following is an example of the auth section in the StackStorm configuration file for the PAM backend.

[auth]
mode = standalone
backend = pam
backend_kwargs = {"service": "login"}
...

Limitations

The python implementation of PAM does not allow authentication as the root user. When utilizing this backend, you will need to authenticate as a non-root user.
