I have an internal application hosted on AWS with https. I need help understanding how to implement SAML authentication to my web application. I am using Spring Boot for my backend and AngularJS for my front end. I am using ADFS as my IP. From what I gather, the following are the steps.
Get a https URL for your application
Create a basic ADFS trust.
Add the roles on ADFS
Get a metadata URL and enter it in your application.properties.
I am trying to implement SAML for the first time and have confused myself completely. Any thoughts shared would be greatly appreciated.
Your Spring Boot application needs to be a Service Provider (SP) that trusts your ADFS Identity Provider (IdP) and you ADFS IdP needs to trust your SP. This trust is usually done using the SAML2 metadata profile, i.e. the SP and IdP SAML2 metadata files.
You can either design your application as a 'standalone', i.e. no SAML ability and put something in front of it that understand SAML and blocks all requests until the IdP sends attributes. This is how the standard Shibboleth SP works but it needs Apache. The other option is to use the framework to plumb in the SAML capability such as Spring Security SAML

I have an authentication/authorization server that currently uses a local ADAM instance to hold the authentication and authorization information for use by a Service Provider (SP).
What I want to do is change from the ADAM instance to a remote ADFS for authentication and authorization. The remote ADFS talks SAML but the Service Provider (SP) only talks with LDAP (and I cannot change the SP to talk SAML).
This suggests that I need to provide a LDAP to SAML converter (or bridge) to produce SAML messages from the SP's incoming LDAP authentication and authorization requests.
Currently it's like this:
LDAP
SP <------------> Authentication Server
I want it to look like this:
LDAP SAML
SP <------------> Authentication Server w/LDAP/SAML bridge <------------> ADFS
So essentially the current authentication server will cease to authenticate itself and will
merely act as a "proxy" for passing on authentication/authorization requests and relaying
responses back to the SP.
Is this possible?
Does anyone have experience with this sort of effort?
Are there any tools on the Net that could perform this bridge functionality?
The current authentication/authorization server runs on gasp Windows 2003 but I do have the
option of porting it to a newer version of Windows Server.
I have tried using OneLogin with the SAML toolkit/Flask websever, and writing my own Python module for handling the SP's requests but I'm getting bogged down with that code (and exposing my own Python limitations)
I also tried SimpleSAMLphp but determined that the LDAP stuff they support is for the IDP side rather than the SP side. The system performs SP-side initiatation.
Have you considered using ADFS to LDAP directly?
Your application would then use ADAL / MSAL to connect.
I have an internal app that allows users to sign in using Azure AD. On authentication, a SAML assertion is returned. However, some of the calls that the application makes require a JWT. WHat is the best way for me to get a JWT when a user signs in? Or is there a way for me to exchange the SAML for a JWT?
Disclaimer: I'm not expert an any of this stuff; I'm still learning it too and struggling with a similar problem. That said, here is my understanding.
I'm pretty sure there is no connection between SAML and JWT. Not a surprise, given that SAML 2.0 dates back to 2005 and JWT got started around 2012. So it's logically impossible for the SAML spec to say anything about JWTs.
If my understanding is correct, you have two options:
Do not use SAML directly. Instead of interacting with a SAML IdP (identity provider), use OpenID Connect and OAuth 2.0 with a provider that acts as an authentication broker. Configure the broker to act as service provider to your chosen SAML IdP. Configure your application to act as relying party (OAuth terminology, I think?) on the authentication broker. Then your app is OAuth 2.0/OpenID Connect/JWT all the way down. Your only interaction with SAML is configuring an authentication broker. Main downside is now you have to select and pay for an authentication broker as well as a SAML IdP.
Write your own authentication/authorization service to consume SAML assertions and issue JWTs. This might be necessary anyways, depending on how you need to represent authorization info in your JWTs.
We have requirement of build .NET based plugin/component for enabling Authentication against multiple IDP providers like ADFS, Azure AD and Shibboleth based on DB configuration. i.e, depending on the configurable parameter the anonymous user will be authenticated against any one of the IDPs like ADFS, Azure AD or Shibboleth IDP.
Our application URL ("https://www.contoso.com/ProcessToken.aspx") will be registered as RP Identifier in all of the 3 providers.
We won't make any web.config changes for any of the providers.
At run time, User will access common page(Proesstoken.aspx) who needs to get redirected to the any of the Login page URLs at the provider (ADFS, Shibboleth, Azure) for Authentication based on User Organization. (For ex: User A to ADFS, User B to Shibboleth etc)
After Successful authentication at the IDPs the user needs to get redirected by the provider (ADFS/ Shibboleth/ Azure AD) to the RP Url registered.
In the redirected page (ProcessToken.aspx), we are planning to get the security token and decipher the claims required.
The main intention is to decouple authentication away from application logic and it should be extendable to other providers in future.
PS: Considered options like OWIN Authentication Middle Tier, .NET Component etc.
Need guidance on How and where to start.
Have a look at IdentityServer 3 which implements this multi-auth scenario or OWIN : ASP.NET MVC application with multiple authentication options.
The main point is that you use NuGet to download all the protocols you require and than use OWIN to pull them all in via app.use.
You can configure ADFS to have Claims Provider Trust with the other IDP's Owin will acknowledge the authentication. The difficult part will be reading the attributes from the tokens. ADFS under the covers in conjunction with the Owin framework use ws-federation, I have not figured out how to read the SAML.
What gets confusing is that at one time the answer was WIF but now that 4.51 has been released, WIF was moved into Owin. The documentation for a multi-tenant application is sketchy at best.
I have successfully configured a SAML 2.0 Identity provider in a separate Weblogic domain
We have an ADF application deployed in Weblogic in another domain with non-SAML form-based authentication (ReadOnlySQLAuthenticator is used to verify credentials)
I want to configure the second domain as a Service Provider (to enable the existing application to login with the Identity provider.
I did the folowing:
Configure a SAML 2.0 Identity Asserter
Enable the Service Provider in the federated services for the server
Add and enable the "service provider partners" and exchange metadata on both IDP and SP side
Configure the "redirect URI" on the SP side
Add the SAML 2.0 Authenticator (the documentation doesn't mention this, but some blogs do)
This should be enough to make the SSO work, but it doesn't.
opening the application doesn't trigger a redirect to the IDP (even when the URL is configured in the provider partner config)
after logging into the application, other applications still have to log in with the IDP (SSO doesn't work)
The "other application" is the Spring SAML sample application and I verified that SSO works with 2 different instances of that app (which means the IDP side should be configured correctly).
We've had some Oracle experts come over to our company to solve various issues.
In the end even they could't help with this and suggested that SAML support may not really work that well.
They suggested that we try to use Oracle Access Manager, that's supposed to support both OAUTH and SAML. We didn't get to that yet and maybe never will.
Still if you need SSO in Weblogic, you could give it a go.
I am looking with Apache shrio framework. Looking at it authentication and authorization features can i build Identity server provider using shrio framework.
Is it possible to have features like,
Single Sign On
SAML support
Federation based on attributes
Do we need to write everything from scratch or shrio has some API's to handle such kind of features.
I read the documentation where they say about having SSO features based on Sharing of user session with multiple organizations . But i did not see any direct support API's to handle this.
To act as an IDP what shrio gives and what it does not support?
Please suggest.
Thanks,
Sohan
Shiro is a security layer that sits in front of your application. It is a security framework for a (SP) Service Provider that will issue an Authentication Request to your IdP (Identity Provider).
Open source IdP implementations that support SAML:
http://www.gluu.org/docs/
https://shibboleth.net/
This Stack Overflow question covers a way to use SAML to authenticate your user before they reach the application and provide the user's credentials as part of a http header.
Integrating Java Web App with SAML SSO
An alternative to installing and maintaining your own IdP.

The cost of developing, securing, and maintaining your own identity provider are likely much higher than paying a monthly fee.
