This is a Python script designed to run as an [ejabberd external auth](https://docs.ejabberd.im/developer/guide/#external) program, and validate user accounts directly from a [Mastodon](https://github.com/tootsuite/mastodon/) installation's database.
The code is derived from [ejabberd-auth-mysql](https://github.com/rankenstein/ejabberd-auth-mysql) and is licensed under the GNU GPLv3.
Discussion, questions and/or just saying hi in the [Chinwag Social Beergarden](xmpp:beergarden@rooms.chinwag.org?join) MUC (beergarden@rooms.chinwag.org) is welcomed!
Edit the `auth-mastodon.py` file and add database connection credentials at the top. Moving this to a config file is next on the TODO list, as this makes updates an awful process. Sorry.
I recommend not using your main Mastodon database user account for this, and instead granting SELECT privileges on the Mastodon *accounts* and *users* tables to your ejabberd user instead.
The code here does not attempt any modification to the Mastodon tables at any point, so there's no reason to give it more than read-only rights.
Then configure ejabberd to use `auth-mastodon.py` as an external authentication provider, as described in the [ejabberd docs](https://docs.ejabberd.im/admin/configuration/#external-script):
```yaml
auth_method: external
extauth_program: "/path/to/auth-mastodon.py"
```
## To Do
1. Move all database and config elements to a simple file to be stored in /etc/ejabberd or similar
2. Verify domain part of request somehow. Maybe define a canonical domain to be used in config? Does this gain us anything at all?
3. Better error handling. Would be good to be more descriptive in the logs, perhaps.
4. Setup documentation is very brief, maybe include how to grant minimal permissions via pgsql.
