Interoperability with OAuth2 Server Library for PHP

[tgal]

When trying to get Vouch to talk to a Symfony app with this PHP library (see https://github.com/bshaffer/oauth2-server-bundle) after successful authentication Vouch aborts with this error message:

INFO    OpenID userinfo body: %!(EXTRA string={"id":"me@myemailprovider.com","name":" "})
ERROR   json: cannot unmarshal string into Go struct field User.id of type int

The email address (me@myemailprovider.com) in the OpenID userinfo body is the primary user id in the Symfony app and I am expecting it in the X-Vouch-User HTTP header.

Any hints what's wrong here?

Instead of returning a field named 'id', can you get it to return 'email'? May need to put a number in the 'id' field too.

No, unfortunately it is not possible to remove the 'id' field or have it return an integer.

Unfortunately this aspect of OIDC is not specified. Everyone returns slightly different user information. Even if we turned 'id' from int to string there would be other changes necessary. It would necessitate establishing a new 'oauth.provider' and getting the id copied to 'User.username'. Its probably easier to hack the php library but if you cared to work on a PR I would be happy to support.

Thanks for your reply, after all it was possible to have PHP return the OpenID userinfo as 'email' and now it all works. Thanks for providing this excellent piece of software!

Oh I'm so glad! Would you be able to provide your config (redacted) for use with the php library and psuedocode for any modification you needed to make to get it to generate the email field? I'd love to link to the thread from the README. Thanks much!

It was not the PHP library's fault and least of all, Vault's. The PHP app's user_info_url endpoint now simply returns {"email":"me@myemailprovider.com"} instead of formerly {"id":"me@myemailprovider.com"}. It was a change in the way the PHP library was used. Thanks again!
