When I am connected on a Windows Server (for example 2012R2) on which ADFS is installed, SSO with Microsoft365 is working well. What would be fastes way to determine, which SAML Version, 1.0 or 2.0, is used in this envrionment SSO?

I'm writing some SSO code, that will allow any IdP that supports SAML to authorize with my code.
I need an IdP Simulator that can provide me a metadata URL with the Idp config so that I can test my code. (I'm providing in my code the SP config).
I search but couldn't find some kind of simulator, all I found were tools that manage the apps if I provide both the IdP and SP configs, which is not what I'm looking for.
Thanks a lot!
SAMLtest.id is a free SAML 2.0 testing service that allows you to test your SAML-compliant Service Provider (which is effectively what you have, based on your description). You need to upload a metadata document representing your SP / your application, and you'll be able to download the SAMLtest metadata to use to form your half of the integration.
This is effectively the new version of TestShib, which shut down a number of months ago due to lack of community support, and I use it relatively regularly.
Good luck!
Alternatively you could also use SSOCircle , which offers a free of charge SAML IdP as well (https://www.ssocircle.com/en/portfolio/publicidp/). E.g. it is configured as a default SAML IdP for Spring Security SAML extension.
(I) How to build and run Shibboleth SAML IdP and SP using Docker container at GitHub repository allows you to build and run a standalone IdP Simulator at your own testbed. Running a standalone SAML IdP Simulator by yourself allows you to test your SP code and debug your SAML SP log by checking server logs of both IdP and your SP developed by you.
(1) Download the source code from How to build and run Shibboleth SAML IdP and SP using Docker container at GitHub repository
git clone https://github.com/winstonhong/Shibboleth-SAML-IdP-and-SP
(2) Copy your SP metadata file into
shibboleth-idp-dockerized/ext-conf/metadata/
(3) Extract IdP metadata file "idp-metadata.xml" from
shibboleth-idp-dockerized/ext-conf/metadata/
and upload it to your SP server developed by you
(4) Follow the README instruction to run OpenLDAP server and SAML IdP server using Docker container
(5) Run your SP server developed by you
(6) Now you can check the server logs of both Shibboleth IdP and your SP server to debug your SP code.
In addition, shibboleth-sp-testapp/ folder provides the reference SP configuration for your SP server developed by you.
(II) Another StackOverflow question Setting up a new Shibboleth IdP to work with an existing SAML SP discusses the SAML configuration between IdP and SP.
(III) TestShib is the online Shibboleth IdP simulator built and run by the Shibboleth community. It is exactly the same as the above standalone Shibboleth IdP simulator built and run by yourself.
As a requirement I need to configure 2 enterprise applications using SAML token.
Due to following listed constraints I need to write individual services for token generation and token signing.
The Constraints are:
No IdP(Identity Provider) available. No associated metadata file available.
Need to use SAML 1.1 version
Need to self-sign the SAML Response.
As part of POC I am able to generate SAML Token using 2.0 version by writing a service which is forwarding to Signing service for signing. I am able to sign it by generating certificate\keystore using Windows keytool command.
Although For SAML 1.1 Implementation using OpenSAML library I am unable to generate the SAML request message in proper format. I looked for additional libraries which could help like WSS4J which has SAML Token Profile Generator.
Also some configuration around IBM Websphere Application server (SAML Token Generater) as that is the used for hosting an application. Still could not implement the solution using the above options.
Questions:
Is it possible to do a SAML implementation without using a IdP Server ?
Can I use IBM Websphere Application Server(WAS) as IdP Server?
Can WAS be utilized for generating STS tokens ?
Any library like OpenSAML, WSS4J which can be helpful to generate & Sign SAML Tokens easily for SAML 1.1 version ?
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
We would like to use SAML 2.0 for a Single Sign On solution. As a typical Microsoft shop, we prefer to use Microsoft components as much as possible. Windows Identity Foundation supports SAML 2.0, but the extension is still in Community Technology Preview (CTP) for more than a year, with no information anywhere on future course. See http://blogs.msdn.com/b/alikl/archive/2011/05/16/windows-identity-foundation-wif-extension-for-saml-2-0-protocol-community-technology-preview-ctp.aspx
I came across an inspiring article by Michèle Bustamante: http://www.devproconnections.com/article/federated-security/generate-saml-tokens-using-windows-identity-foundation She actively promotes WIF + SAML 2.0, but nowhere in the article she talks about CTP or final release. Neither could I reach her for a clarification.
With this background, is it safe to use WIF Community Technology Preview for SAML 2.0 or stick with SAML 1.1? Does SAML 2.0 offer significant advantage over SAML 1.1? Is the future of SAML 1.1 in question?
Any other alternatives?
You should clarify whether you're talking about SAML 2.0 protocol (e.g SAMLP) or just the token type. WIF RTM supports SAML 2.0 tokens, but not SAMLP.
So if it's just SAML 2.0 token support you need, WIF RTM is sufficient, though WIF extensions CTP does add some SAMLP support.
If you're looking for a SAMLP solution and you're a Microsoft shop then you should consider ADFS 2.0.
ADFS 2.0 would do "protocol transition": it will talk SAMLP with the Identity Provider and WS-Federation with your app (both use SAML "Tokens"). WIF supports WS-Federation.
Take a look at Identity Server which is a STS that does use SQL Server for authentication. You can easily federate this with ADFS.
From what I remember about reading the licence agreement for the CTP release, it's just out there for comment - you can't use it e.g. in a Production environment.
As per #Eugenio, WIF only supports WS-Federation.
How were you intending to "stick with SAML 1.1"?
Update: What I suggest is that you use Identity Server to do the authentication against the DB. Your WIF applications are bound using FedUtil to Identity Server. You then federate Identity Server with ADFS. Your external parties use SAML to talk to ADFS and ADFS will handle the plumbing to enable them to authenticate with the Identity Server DB.
Note that WIF doesn't support SAML at all.
I have a requirement to integrate Umbraco membership with SAML Web SSO.
I have never integrated with it before and would like to have a bit of advise:
Are there some existing modules for SAML WebSSO login in Umbraco?
Could you recommend the approach/articles to start with?
How hard could that be?
Thanks in advance, Anton.
If you're new to SAML 2.0, the wikipedia page is a worthwhile read to understand the main concepts of SAML.
A toolkit for Umbraco seems to exist: http://digitaliser.dk/resource/404629
This toolkit explains the integration with a specific SAML 2.0 Identity Provider, but as SAML 2.0 is norm, it should be compatible with any SAML 2.0-compliant IdP.
The other solution is to add the SAML 2.0 Service Provider manually in Umbraco. A good start point may be the Windows Identity Foundation SAML 2.0 toolkit released by Microsoft in May, that include code samples: http://connect.microsoft.com/site1168/Downloads/DownloadDetails.aspx?DownloadID=36088
