I would like to know if there is way to configure Microsoft ADFS to assgined more than one roles user. Can I get the corresponding SAMLResponse XML for this ?
There are a number of ADFS claims rules "Token Groups as xxx".
Map one of these to Role - depending on what you want.
ADFS will then send all the security groups that the user is memberOf as Role.

At the moment we're asking users to enter role names when restricting APIs by roles. Users (API publishers) have to know the roles beforehand. If it's LDAP then they have to use an LDAP browser or ask an admin to provide a list of roles.
After typing a role we're doing a validation check to make sure role is valid. If we can extend this to list out / browse all available roles and let the user to select a subset, that'll provide a better user experience
Currently, WSO2 APIM publisher rest API does not have such resource to get the list of roles. It only has a role validation endpoint.
I am setting up an instance of WSO2 API manager, and want to give developers access to the API "store" pages by linking it to my existing OpenID Connect identity server (OpenAM). I've added the OIDC configuration into the store configuration file (wso2am-2.6.0/repository/deployment/server/jaggeryapps/store/site/conf/site.json) with all the details of the authorise, token, userinfo endpoints, etc.
When users click login in the store, it is correctly redirecting them to OpenAM to login, and passing an access token back to the store app. I've also ensured some of the required claims are returned from the userinfo endpoint (like preferred_username). I'm also returning a "groups" claim listing the groups the user should be in "subscriber" for example.
The claims I'm returning from userinfo are:
{
"address":{
"formatted":"My House"
},
"given_name":"Danny",
"family_name":"Developer",
"name":"Danny Developer",
"preferred_username":"Danny Developer",
"groups":[
"subscriber"
],
"email":"adam.hatherly#nhs.net",
"sub":"developer1"
}
However, whatever I try with claims and group names, the store still gives the error message "User is not permitted to log in to the Store.". I assume there's something else I need to add in either the access token or userinfo endpoint
claims list to make the store app accept the user, or some other config in the store or carbon console?
The reason for the user login issue is that the user does not have relevant permissions to log in to the store. User needs to have internal/subscriber role assigned to it. Since the user is coming from OpenAM and APIM does not have any information to authorize it, login fails.
For this either you should share the user OpenAM user store with APIM (say a shared LDAP) and assign users with internal/subscriber role or use a custom code to add the user to the APIM user store and assign the role.
Another easiest option is to create a user in APIM side (add a dummy password) with subscriber role. but this is not a suitable solution if you do not know all the users
I have an ADFS environment with a configured a second Claim Provider along side the default Active Directory Claim Provider.HomeRealm discovery is "disabled" because I have set my Web Application to only use the non-AD Claim Provider.The current claim rules are configured so that claims coming from the second Claim Provider are included in the Auth token issued to clients connecting to my Web Application.
Is it possible to configure the claim rules to have claim data coming from both Active Directory and the second Claim Provider be included in the Auth token?
For example: Google[mail] + ActiveDirectory[samAccountName] => Auth Token
Yes, it is possible. The key point is how to map "user" returned from the second Claim Provider trust's to an AD user. Usually the token must contain a claim which can be used to query a respective user in AD. The following link shows how to query more claims from AD for such a scenario:

I have followed this article to build demo app with on-premise ADFS federation.

I am able to get needed information for user using simple code
Dim UserEmail = System.Security.Claims.ClaimsPrincipal.Current.FindFirst(System.IdentityModel.Claims.ClaimTypes.Email).Value
But how I can get user groups where the username belongs and check if user account is member of Windows group in Active Directory?
I have tried to use System.Security.Claims.ClaimsPrincipal.Current.IsInRole to check if user is in group, but it won't work
In ADFS claims rules, you need to configure a rule "Send LDAP Attributes as Claims" / "Token Groups - Unqualified Names" and map to "Role" as the "Outgoing Claim Type".
ADFS then provides all the security groups the user is memberOf in Role format and WIF maps them to the IsInRole construct.
With this is enough.
ClaimsPrincipal.Current.AddIdentity(new ClaimsIdentity());
ViewBag.Name = ClaimsPrincipal.Current.FindFirst(ClaimTypes.Email).Value;
:)
I just don't still get Claim Based Authentication/Authorization workflow.
The application allows authentication via Facebook.com
After the user is authenticated, an admin can give her/him a claim of having the role of Manager, which creates another claim (where?)
Of course, this claim won't be on the facebook.com server, question 1: where should that claim be stored?
When the user log in again later, I get the claim of facebook.com and I should get the claim from the application. and merge them?
How is the workflow? Trying to understand claims in practical usage.
Basically, Facebook tells me that I'm john#doe.com, and 'field in the blanks' adds a claim that I'm also a manager of domain.com
then I pass those claims to domain.com?
How should I configure in asp.net the application at domain.com to trust Facebook and 'filled in the blank piece' and request claims from both?
I guess I'm using external providers for Authentication and my own provider for Authorization, how this is created on ASP.NET (web API / MVC)?
UPDATE (for clarification)
Let's get backwards. I create a web application where users can register.
'Somehow' there's an trusted ClaimsBased authority somewhere (this should be another application??) where I request the claims for a particular user to see if have particular rights on my application.
So I imagine something like :
/authserver/claims
and my validation checks if X claim is met to do certain operations.
later I add to Facebook. now I have
/facebook/claims
which tells me the user is X
and
/authserver/claims to see if can do operation X on resource Y.
how this is managed on ASP.NET? and where my own claims should be created/exposed/developed.
I think I'm missing something fundamental here.
I think the important thing to understand is the difference between authentication and authorization.
Authentication - the act of confirming the truth of an attribute of a datum or entity.
Authorization - the function of specifying access rights to resources, which is related to information security and computer security in general and to access control in particular.
So, typically for secured system, the workflow starts with Authentication. When a user first connects/uses a system, then are not authenticated (lets say this user is of a type/group Anonymous). The act of the system determining the user is not authenticated is an Authentication in and of it self. Based on being Anonymous, then the act of the system determining what that type of user anonymous has access too is now authorizing what the user can do. For very secure system, the only access anonymous has is to the login screen/page. Once logged in the user is assigned a unique identity and assigned some type of group policy/role (if not already created).
with a web-based application and having a website (#1) authenticate for another website(#2) it becomes a bit more complicated. When I log into StackOverflow(#1), I use my Gmail(#2) account. I get redirected to Google with some special way for Google to know that the page I came from/to go back to. This could be a special key/url combination or for less restrictive access, usually has to do with return url (after I say, yes, where I go back too). Google will create a special authentication token that is specific to the url I am returning to. It is tied to the URL because that means that my token on StackOverflow won't allow me or anyone else to log into say NewEgg for example (in other words someone at StackOverflow with access to the database can't use my token to authenticate as me on some other website, but technically they could log in as me on StackOverflow, but they own the website, so that doesn't really matter). Now I am authenticated on StackOverflow (but technically StackOverflow doesn't even need to know any information about me, just my Token).
On StackOverflow as a new user, a new account is created. This account probably has a one to many relationship to my unique account on Stack Overflow and multiple of logins (and type of logins, OAuth, OpenID or SO Login). Once the account is created, I have whatever access they have setup by default. If I need more or some trigger (lets say based on my Reputation points :) I now have access to Administrative functionality (given some role). That role is tied to my account and indirectly tied to my authentication. This means that I can create additional logins (say a Local SO Login) but keep my Account.
As for each Authentication resource (Google, Facebook, etc) there will be difference schemes for Authentication, but there will always be at least a token (or more than one token) for a website to say who I am (in a generic way).
So website #1 (Stack Overflow) has requested website #2 (Google) to Authenticate me. But only website #1 knows what am I Authorized for.
For role specific functionality, there are a good number of answer on SO dealing with ASP.Net Identity and the Role Manager:
Creating Roles in Asp.net Identity MVC 5
mvc 5 check user role
A much more Indepth look into Identity with MVC - Extending Identity Accounts and Implementing Role-Based Authentication in ASP.NET MVC 5
If you're using ASPNET.Identity (http://www.asp.net/identity/overview/getting-started/introduction-to-aspnet-identity), you can add a Role claim type to the user. It'll be associated with the userlogin, so when the user authenticates with Facebook, these user claims will be added and available in MVC.
See the following code fragment:
var acRes = await UserManager.AddClaimAsync(userId, new Claim(ClaimTypes.Role, "MyRole"));
