OpenId support is simpler to implement than OAuth. Google and Yahoo providers are supported by default, others are supported by POST method providing endpoint URL.

OpenId backends can store extra data in UserSocialAuth.extra_data field by defining a set of values names to retrieve from any of the used schemas, AttributeExchange and SimpleRegistration. As their keywords differ we need two settings.

Settings is per backend, so we have two possible values for each one. Name is dynamically checked using uppercase backend name as prefix:

SOCIAL_AUTH_<uppercase backend name>_SREG_EXTRA_DATA
SOCIAL_AUTH_<uppercase backend name>_AX_EXTRA_DATA



Settings must be a list of tuples mapping value name in response and value alias used to store. A third value (boolean) is supported to, it’s purpose is to signal if the value should be discarded if it evaluates to False, this is to avoid replacing old (needed) values when they don’t form part of current response. If not present, then this check is avoided and the value will replace any data.


The OpenId backend will check for a username key in the values returned by the server, but default to first-name + last-name if that key is missing. It’s possible to indicate the username key in the values If the username is under a different key with a setting, but backends should have defined a default value. For example:


This setting indicates that the username should be populated by the nickname value in the Fedora OpenId provider.
