Dotnetopenauth CTP v4 - Using Password workflow - dotnetopenauth

I have a client who wants to use Oauth 2 however they want handle the passwords at their end due to the way their systems work (long story).I believe there is an oauth workflow that supports this. Would dotnetopenauth support this? Cheers, Chris. I will be designing a provider for them to use.

If it's in the OAuth 2 spec, DNOA will very likely support it when the spec is finalized and DNOA releases a new version that implements it.
Personally, I very much dislike that particular workflow.

Can I use AEM as OAuth 2.0 client?

Does Adobe Experience Manager support OAuth 2.0 as a client? I mean AEM connecting with an external application which plays a role of authorization server and resource provider.
I could not find any examples of such usage - AEM is usually presented as an authorization server and resource provider for other client applications.
AEM provides an number of authorization integrations. Maybe you can switch to SAML, which works pretty good out-of-the-box. I once integrated AEM with Keycloak with good results (but using SAML).
Regarding OAuth most documentation is dominated by AEM as an OAuth provider. They integrated Apache Oltu (which is end-of-life anyway).
But AEM provides an OAuth client as well. But it needs a custom extension for each provider. Out-of-the-box are only implementations for Twitter and Facebook available. But there seems also Github and IMS (Identity Management from Adobe Managed Services) to be available.
Please check also Package Share. But I don't know what is available there. And you probably need support from Adobe, to judge the quality and usefulness of such packages.
If you have to implement your own Provider-Extension, the best starting point I found was here:
https://aemcorner.com/adobe-granite-oauth-authentication-handler/
You are basically free to build whatever you want, as AEM is basically nothing else but a Java application. But you might want to keep in mind, that the standard applications of AEM are delivering rendered HTML from the dispatcher in the end. You want to have as little load on the publishers as possible.
So, when authorisation of resources is a technical- or business concern, you might need to dive deeper into SPAs or at least async loading of resources as JSON.

oauth 2.0 integration with peoplesoft

Our existing customer base is in peoplesoft and we are developing lot of mobile applications. Hence, we would like to use oauth 2.0 for authentication and authorization, but i cannot find any way to integrate the two.
Does PS implement OAuth? If they don't then you'll be out of luck. A quick search indicates they support SAML for SSO (on their web sites). You will probably have to describe a little bit more what you are doing, and why you think OAuth is the way to go.
Note that being mobile doesn't necessarily mean you have to implement OAuth.
This is a very late answer, but as of PeopleTools 8.58, PeopleSoft applications support OAuth2 for REST services. The caveat is that only Oracle IDCS is able to be used as an authorization server. There may be a plan in the future to support other authorization servers.
Cf. https://blogs.oracle.com/peopletools/what-peoplesoft-is-doing-with-oauth2-in-858 and https://support.oracle.com/knowledge/PeopleSoft%20Enterprise/2621182_1.html for more information.

OpenID Connect Provider implementation

Is there any sample of implementation of OpenID Connect Provider in .NET?
DotNetOpenAuth doesn't seem to support this standard.
Yes, IdentityServer is an openid connect provider. There are lots of samples of relying parties, provider configurations and a resource server api. See here for the examples: https://github.com/IdentityServer/IdentityServer3.Samples/
It seems to currently be the only "certified" open source .NET (C#) implementation. See http://openid.net/developers/libraries/
I would expect Microsoft to release their OP pretty soon, named WAAD - Windows Azure Active Directory Server: http://www.gluu.co/waad-interop
Are you sure you need an OpenID Provider? If you need Relying Party code, I recently saw this quick article: http://www.gluu.co/simple-connect-client
If you really need an OP, perhaps you should consider OX: http://ox.gluu.org
Who really cares what language the OP is written in? What you want is an easy way to administer the thing... and OX provides an excellent management Web UI (oxTrust).

Authentication for MVC4 Web Api

I'm trying to secure my MVC4 Web Api. Actually, I just really need an identity provider with some light security. My service is similar to twitter, from a security standpoint, there's not a lot of private data, but the service does need to know the userid for the caller.
It's also important to know that the web service will only be consumed by mobile devices right now, although a website may accompany it at some future point.
S.O. and the internet have led me to Thinktecture.IdentityModel, but man it seems complex and I can find exactly zero documentation or samples. I also haven't yet had a pleasant experience with claims-based authentication. I don't have a claims server, token provider, or anything like that, and it seems like you would need that to use this method. This all seems far to heavy for my situation.
I've also read about people implementing their own HMAC solution (https://github.com/cuongle/WebAPI.Hmac) or using OAuth (https://github.com/maksymilian-majer/DevDefined.OAuth) but these also seem a bit complex (I've read that OAuth without the helper class is enough to make the best developers cry, and I'm not the best). Janrain looks like it might work, but it looks like you have to pay for more than 2,500 authenticated users per year ...
What is the best way to implement a simple identity provider and security for Web Api?
Thanks!
I have attempted to answer a similar question to this before Create an OAuth 2.0 service provider using DotNetOpenAuth where I highlighted the Thinkecture Identity Server. The Setup instructions not too difficult (IMHO) The installation video is here and should help a lot.
I have updated my older answer with this too but there is also a fairly lightweight O-Auth 2.0 implementation example here Sample code here http://code.google.com/p/codesmith/downloads/detail?name=OAuth2.zip&can=2&q=#makechanges
Have you also read this well articulated question here Authenticating requests from mobile (iPhone) app to ASP.Net Web API (Feedback requested on my design)
Well, security is hard :)
As for Thinktecture.IdentityModel -- this is a token processing library (among other things) that you'd use in your WebAPI application. You'd use this so you don't need to do the logic to accept tokens (basic auth, SAML, SWT, JWT). Claims are just a side-effect.
If you're looking for an identity provider, then the sister open source project Thinktecture.IdentityServer is in beta for version 2. It's an identity provider that supports a custom database and issues tokens. The project URL is:
http://thinktecture.github.com/Thinktecture.IdentityServer.v2/
In response to the problem of finding example code as documentation, consider the samples folder in the Thinktecture github repo: https://github.com/thinktecture/Thinktecture.IdentityModel.45/tree/master/Samples
(Why do you need more reputation to comment on SO than to answer?)

Create an OAuth 2.0 service provider using DotNetOpenAuth

I'm building a web app which will have an api and an authorization service using DotNetOpenAuth. I found this example on how you can authorize using a service provider that already exists but I would like an example on how to implement a service provider that can create tokens, persist them and do evaluation. Is there any great articles or sample providers that I can download?
Update
DotNetOpenAuth has moved on since this was initially posted. I strongly suggest you follow Ashish's advise and take a look at the samples. It contains code to write Authorization Servers, Resource Servers and Clients for all the major flows.
If you wanted a pre built solution, with opensource code
Thinktecture Identity Server is an Open Source .NET security token service. It supports a number of endpoints for authentication including OAuth 2.0 Bearer tokens.
Update this Thinktecture Identity Server is now on version 2 and supports these OAuth 2.0 flows
Resource Owner Password Credential Flow
Implict Flow & JavaScript
Authorization Code Flow
again take a look at the code to see how it was all done and there are samples here to show how to plumb it in.
I hope this helps - these library's and examples have hugely helped us over the past few months.
Update
There is also another example warning, it looks dated of a simple OAuth provider for MVC here Sample code here
There are complete working example for DotNetOpenAuth can be found here - https://github.com/DotNetOpenAuth/DotNetOpenAuth/tree/master/samples
I tried a number of times with DNOA....had to give up, but documented my findings (used Thinktecture in the end)...http://tb-it.blogspot.co.nz/2015/06/oauth-20-frameworks-and-platforms.html
