A security token service implements the protocol defined in the WS-Trust specification. This protocol defines message formats and message exchange patterns for issuing, renewing, canceling, and validating security tokens.
A given security token service provides one or more of these capabilities. This topic looks at the most common scenario: implementing token issuance. A token type URI. A key size value that indicates the number of bits in the key to be associated with the issued token. A key type URI. This will allow you to set up and test claims-aware applications.
This required the following to be installed on your machine before you get started:. In the real world you would be integrating your claims-aware application with an existing security token service that you will have no direct control over. In this example we will set up a test service that acts as a token service and uses SQL Server as the store for user and role information. Any user of your claims-aware web application will be sent here to enter their username and password before being passed back to the application.
This basic site will contain a login form and a default page. Although forms authentication will be enabled, it will not be not linked up to any data store. Security header structure and message examples for authentication modes below follow the "Strict" mode. This section provides example policies for each authentication mode along with examples showing security header structure in messages exchanged by client and service.
These authentication modes are constructed using the transport binding described in SecurityPolicy. For the other authentication modes the token appears as a signed endorsing token. Appendix C. The following example security headers show the Strict layout for a given authentication mode. The value of the "Derived Keys" property for the tokens in all cases is "false".
With this authentication mode, the client authenticates with a Username Token which appears at the SOAP layer as a signed supporting token that is always sent from the initiator to the recipient. The service is authenticated using an X. The binding used is a transport binding. With this authentication mode the client authenticates using an X. With this authentication mode the client does not authenticate to the service, as such, but rather presents a token issued by a Security Token Service STS and proves knowledge of a shared key.
The issued token appears at the SOAP layer as an endorsing supporting token that is always sent from the initiator to the recipient. The binding is a transport binding. With this authentication mode the client authenticates to the service using a Kerberos ticket.
With this mode a negotiation protocol is used to perform client and server authentication. Kerberos is used if possible, otherwise NTLM. The service is additionally authenticated at the transport layer by an X. The service is also authenticated using an X. For example, there was no way to provide signature and encryption protection for messages using only service X token. Now a temporary key encrypted for the service's X.
Note: Here There is an option for to update the federation metadata on a routine basis. RP would only come to know about when federationmetadata will be updated, else say if someone removed a Claim and metadata is not updated it will allow to get the that Claim but actually at runtime you would nto get that claim which will not be a good condition.
One should always have the metadata in updated form. After clicking Finish. Lets run the application: Now if you run the application. It will throw an exception as. This is an issue with it and I have made a small post on it. You can get it resolved easily. Please check this. Now after changes it will run smoothly and It will take you at login page that is provided by STS. This is default login page provided STS, here you dont need to write password just put some name and click on login as below.
It will redirect to another page to STS which will actually initiate the process to create the token and claims.
Then after creating it will be transferred to your website as authenticated user. Now our application is running. As here in STS we have a sample login page the uses Forms authentication and by default authenticate every user. So one can additional claims here. One file named CustomSecurityTokenService. In this file there is a method GetOutputClaimsIdentity actually creates the claims. We need to add the claims here I have added few.
I have added two claims Email, Gender as above. These Claims will be available at ASP. NET website Relying Party. The same Identity provider can be used in multiple application. To read the claims you need ClaimsIdentity of the logged in user and it is available in User Property.
I have read the Claims at my page. I have created a dynamic table and shown the claim in that. Now you can see that it is very easy to read the claims and this can be used in further processing.
I hope the above sample will help a lot. In my new post of this series. I will discuss another technique to implement use Claim based Authentication which is widely Used Called Identity Federation.
Hi I am very excited about this tecnhology. In your example when we get redirected back to the RP site the web app still crashes. Another thing, you dont explain how to get the claim info and use it in the web app.
