 Under the hood, AWX uses [open-source TACACS+ python client](https://github.com/ansible/tacacs_plus) to communicate with the remote TACACS+ server. During authentication, AWX passes username and password to TACACS+ client, which packs up auth information and sends it to the TACACS+ server. Based on what the server returns, AWX will invalidate login attempt if authentication fails. If authentication passes, AWX will create a user if she does not exist in database, and log the user in.
