Flat file backend supports reading credentials from an Apache HTTPd htpasswd formatted file. To manage this file you can use htpasswd utility which comes with a standard Apache httpd distribution or by installing apache2-utils package on Ubuntu / Debian.

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 flat-file backend.

[auth]
mode = standalone
backend = flat_file
backend_kwargs = {"file_path": "/path/to/.htpasswd"}
enable = True
use_ssl = True
cert = /path/to/ssl/cert/file
key = /path/to/ssl/key/file
logging = /path/to/st2auth.logging.conf
api_url = https://myhost.example.com:9101
debug = False

The following is an sample htpasswd command to generate a password file with a user entry.

htpasswd -cs /path/to/.htpasswd stark
