Authentication Hooks

This documents the hooks that are currently available for authentication plugins. If you need new hooks for your plugin, go ahead a submit a patch.

What hooks are available?

‘authentication’

This hook just needs to return True as this is how the MediaGoblin app knows that an authentication plugin is enabled.

‘auth_extra_validation’

This hook is used to provide any additional validation of the registration form when using mediagoblin.auth.tools.register_user(). This hook runs through all enabled auth plugins.

‘auth_create_user’

This hook is used by mediagoblin.auth.tools.register_user() so plugins can store the necessary information when creating a user. This hook runs through all enabled auth plugins.

‘auth_get_user’

This hook is used by mediagoblin.auth.tools.check_login_simple(). Your plugin should return a User object given a username.

‘auth_no_pass_redirect’

This hook is called in mediagoblin.auth.views in both the login and register views. This hook should return the name of your plugin, so that if basic_auth plugin is not enabled, the user will be redirected to the correct login and registration views for your plugin.

The code assumes that it can generate a valid url given mediagoblin.plugins.{{ your_plugin_here }}.login and mediagoblin.plugins.{{ your_plugin_here }}.register. This is only needed if you will not be using the login and register views in mediagoblin.auth.views.

‘auth_get_login_form’

This hook is called in mediagoblin.auth.views.login(). If you are not using that view, then you do not need this hook. This hook should take a request object and return the LoginForm for your plugin.

‘auth_get_registration_form’

This hook is called in mediagoblin.auth.views.register(). If you are not using that view, then you do not need this hook. This hook should take a request object and return the RegisterForm for your plugin.

‘auth_gen_password_hash’

This hook should accept a raw_pass and an extra_salt and return a hashed password to be stored in User.pw_hash.

‘auth_check_password’

This hook should accept a raw_pass, a stored_hash, and an extra_salt. Your plugin should then check that the raw_pass hashes to the same thing as the stored_hash and return either True or False.

‘auth_fake_login_attempt’

This hook is called in mediagoblin.auth.tools.check_login_simple. It is called if a user is not found and should do something that takes the same amount of time as your check_password function. This is to help prevent timining attacks.
