We have something of a special case. We have privileged devices for which we will use service accounts and certificates/JWT based authentication.Then we will have a user (employee of ours) perform a second log in to the application running on the device. The particulars don't allow us to use a browser in this instance. (For one thing, the user's credentials are not a username/password -- I've had to create a special authenticator for this purpose. But this isn't the only reason.) So, to Brian's question, we are not embedding these credentials in our code.
Since the device is trusted, we could use the password credentials grant. However, since this is a fairly high-security situation we'd prefer not to be sending access tokens over the wire, particularly if we're only relying on TLS for encrypting the token.
We could, on the other hand, use the authorization code flow--I'd just have to follow the redirects and dig the form action out of the form that's returned in the challenge page. I was just wondering if there was some way to access that URL other than by chomping on the HTML, e.g., by using a different "Accept:" header.

Then use service accounts and you can also use public/private key based auth here (client credential flow from oauth2).b) Is it a user logging in through a non-browser based application? Then the ideal option if possible is to embed a web browser and use the authorization code flow. The alternative is to use direct grant (resource owner credential grant flow from oauth2).c) Is it a background process invoking a service on behalf of users when the users are not online? Then use offline tokens.On 27 April 2016 at 17:17, Aikeaguinea <aikeaguinea@xsmail.com> wrote:As I understand it, using the authorization code flow rather than theimplicit flow is recommended where possible.We have a server-side client application, but the user agents makingrequests are not browsers, but instead our own code.I'm not entirely sure how to make the authorization code flow workwithout a browser. For instance, if on the command line I requestcurl'http://host:port/auth/realms/foo/protocol/openid-connect/auth?response_type=code&client_id=test-client&state=state&redirect_uri=http://www.example.com/hello-world'Then (assuming the parameters are correct) I get back an HTML login pagewith a form. In order to submit the credentials, I would need to dig theURL out of the action of the form and then submit a request likecurl -X POST -d 'username=test-user' -d 'password=test1234''http://host:port/auth/realms/foo/login-actions/authenticate?code=Ctr79aRsbwPPkC4nEeT2vR9-TuC31uuXngQXoHQH6FE.ef26cfcd-a35b-4d1e-a4f7-49790f6e2f00&execution=a86f56da-9900-4f1d-a461-f18617a2333b'Three questions:1. Is there some reason I shouldn't be trying to implement theauthorization code flow like this?2. Is there a way to get the proper login action back without having todig it out of an HTML form? I've tried adding --header "Accept:application/json" to the command but this has no effect.3. Is there a way of submitting credentials other than by using formparameters? I've tried HTTP basic auth but it doesn't work for me.
