We are looking forward to implement ADFS to implement SSO across our organization for various set of web applications such as (SAP, Siebel, Custom java based, Asp.net etc.).
I understand based on my research that ADFS can be used to achieve SSO for third party applications using SAML. It can act as an identity provider for third party applications. Please correct me if I am wrong.
Can we use the ADFS to implement cookie based SSO for the various internal web based apps which I mentioned above?? (For Ex: CA Siteminder, ORacle Access manager can work with almost every internal web based application)
In other words: we have one application using apache webserver, one using IIS webserver, one using IHS webserver; can ADFS be used to achieve Single sign on with all these applications??? If yes, How ???
Thanks in Advance...!!

ADFS implements SSO via federation using either WS-Fed or SAML 2.0.
If these applications can support these protocols, then yes just federate these products with ADFS and you will get SSO.
e.g. SalesForce SSO with ADFS.
For Java you need a SAML stack e.g. Spring Security.
For ASP.NET, use OWIN or WIF.

I am having a Web Application running on tomcat and hosted on amazon, I want to add it as an SAML Service Provider which allows single sign on(SSO) in onelogin(https://www.onelogin.com/)
I have a free trial account in one login, and In Add App section I can see many applications like salesforce,aws and all but how can I add my own application there ?
I clicked on Suggest an App and and gave my application URL. Is there anyway I can add my own application as an SP in onelogin ?
You can use the SAML Test Connector. It works with any generic SAML Service Provider.
If you also need to add SAML support to your tomcat application, you should know that Tomcat does not have a SAML SP provider implementation itself, so you will need to add SAML support to the java application. For that you can use:
OIOSAML
spring security
java-saml
shibboleth (It requires also Apache).
I am reading alot about federated identity management and technologies like SAML, which can be used for implementing SSO for web applications, and Kerberos, which can be used for implementing SSO für desktop applications.
This is how I understood it so far. If we have the case, that we want to have SSO for a set of web applications and desktop applications, what are the technologies that are available for that? Do I have to combine SAML and Kerberos or is there another technology that fits better?
AFAIK, Microsoft ADFS and Oracle Access Manager are SSO products which supports SAML, Kerberos and other related protocols, does Windows based authentication and thus provide SSO access across webapps and desktop.

we have a web application(Say wA) developed in java and we need to provide SSO login from client web application(Say WB) to WA and the requirement is to do with Okta-(SAML 2.0).
Currently im having the Idp mnetadatak, IDP Single Sign-On URL and Identity Provider Issuer link created from okta
Anybody please help me on this issue , what things to do in my application side to provide SSO login felicity. how to listen SSO request from my APP (WA).
Thanks and regards
In case you would like to add SAML support directly into your application (as opposed to including it for example in reverse proxy such as Apache or IIS), you can use either Spring SAML (with minimal Spring configuration in case you don't use Spring Security already) or OpenAM's Fedlet.
Spring SAML enables applications to act as a SAML 2.0 Service Provider by initializing web single sign-on towards IDP (Okta) and accepting and validating response (SAML 2.0 Assertion) sent back from Okta.
Good approach to implement Spring SAML is to start with the quick start guide which helps you create SAML 2.0 integration with a public SAML 2.0 Identity Provider, then change the IDP to Okta and then integrate the result into your application.
It is also possible to build SAML 2.0 support from scratch (using OpenSAML library), but significant knowledge of the protocol is needed for it to be done securely.
Some application servers also include SAML support (WebLogic, WebSphere, JBoss with its PicketLink library), but such configuration is of course not portable.
This is a classic example of too much information = too much confusion.
I have a ASP.NET web application that uses the usual POST form authentication and would like to implement SSO.
Since we're a Microsoft shop we will use the ADFS 2.0. In order to implement SSO I understand that I will need to have also WIF to process SAML requests?
Do I install the WIF under the same server as the ADFS?
I still want to re-direct failed SSO requests or non SSO requests to use the form, how do I handle this?
Can someone please describe the flow?
Thanks!
ADFS Supports two protocol for authenication.
1) WS-Federation Protocol
2) Web SSO SAML Protocol
*In Ws-Federation scenario*
For SSO between your Application and ADFS (Build trust relationship).
1) Install ADFS & WIF on one server , Create some users in AD.
2) Generate Federation Metadata.xml file in ADFS, save it one place for
future need.
3) Use Windows Azure Access Control Service(ACS) for
simplicity. (It will do all heavy lifting of your authentication
process of token coming from ADFS)
4) Generate Federation
Metadata.xml file in ACS and Import in your ADFS server as relying
party. (give some claims as well)
[http://blogs.msdn.com/b/card/archive/2010/06/25/using-federation-metadata-to-establish-a-relying-party-trust-in-ad-fs-2-0.aspx?Redirected=true][1]
5) Import federation metadata.xml
file from ADFS server to ACS and Add it as Identity provider. (add
claim processing rule)
6) Now in your web Application use WIF
FedUtil Tool and import ACS federation metadata.xml file.
That's it.. you are good to go..
For Web SSO SAML protocol you have to do manual job of coding.
UseCase:
User will hit your application.
User is not authenticated so he will go to ACS and ACS will redirect it to ADFS login page.
User enters credentials. ADFS issue token to ACS with some claims. ACS will
transform incoming ADFS claims and give it to your application.
your application is now authenticated so you can use claims and do
authorization stuff.
You can use URL scheme to check where this request should go to your forms authentication or ADFS authentication.
eg. : http://somedomain.com/forms or http://somedomain.com/ADFS
So you are using SAML to some 3rd party STS?
WIF (out the box) does not support SAML.
There is a WIF SAML extension but this is only CTP (Community Technology Preview) at this point.
WIF is integrated with your ASP.NET application. For .NET 4 and below, there is a separate download. For .NET 4.5, it's integrated.
WIF is just a set of .NET classes inside your application.
You integrate WIF with your ASP.NET application using a tool called FedUtil which is part of the WIF SDK download. (Invoked by "Add STS" inside VS).
The ADFS install installs WIF on the server but this is seperate to your application.
The flow is:
.NET Application --> (WIF) --> (WS-Federation) --> ADFS --> (SAML) --> STS
I'm currently assessing ways to impelement authentication&authorzation in a .NET SOA environment(ASP.NET MVC, WCF).
I have concluded that using Windows Identity Foundation with a STS should fullfill our criteria.
I'm having hard time finding any suitable STS to work with WIF other than ADFS. I know there are multiple options, but there is no documentation/experience available how well these play together with WIF.
Summa summarum, multiple questions:
Is this dumb idea?
Is there any STS product that plays together with WIF smoothly? Any resources on this?
Are there products that allows me to implement centralized(yet scalable) authorization(even with XACML support)?
What is your experience using WSO2 Identity Server with ADFS/WIF?
WSO2 Identity Server has some XACML capabilities but how can these be used in authorization with WCF services?
There is Starter STS
http://startersts.codeplex.com/
which has lately been replaced by the IdentityServer:
http://identityserver.codeplex.com/
It's been for a while and has some features ADFS lacks (like the ability to use a MembershipProvider to authenticate users).
Also, crafting your own STS is relatively easy. There are some good tutorials around, I've also written few posts on this:
http://netpl.blogspot.com/2011/08/quest-for-customizing-adfs-sign-in-web.html
WSO2 Identity Server can be integrated with ADFS. Also it can be run as an XACML engine. XACML engine is exposed to out side as a SOAP end point as well as a Thrift end point.
Disclaimer : I am an architect at WSO2.
No experience of WSO2 but if you don't want to use ADFS you'll have no problems with Identity Server. Both ADFS and Identity Server and more commercial products such as Ping Identity play very nicely with WIF.
