We have an application for which we would like to enable users to login into our application with their own Identity Providers like Google, ADFS etc with SAML 2.0 as protocol.
In this context our application will be SP and Identity Providers will be Google, ADFS.
But currently we don't have SAML implementation at our application, so we would like to use some platform like OneLogin/Okta/Auth0 as middle proxy between our application and IdP so that SAML related handling can be done at OneLogin/Okta/Auth0 and we need to get callback to our application with user details after success login.
Is this possible with any SASS based SAML providers? and how to do it.
Thanks in advance
Yes - connect to Auth0 / Okta via OpenID Connect and then connect the IDP to other IDP via SAML.
So in this context, Auth0 / Okta is a SAML SP.
Have a look here.

I am unable to find Api's on implementing SAML authentication flow for the SP Application programmatically without user's to manually enter their credentials on SAML compliant IDP( SAP IAS) login screen configured for the SP application as a starting point , I have established the trust between the the IDP and SP application ,trying to implement non interactive login from browser , is there any way to implement this approach.
According to the saml standards you can't send password via saml authn request, therefore you will not be able to authenticate from idp without redirecting to idp login using saml. But if you have control over idp you can implement a shared cookie concept to achve this requirement, but then this is no more saml compliant.
SAML was never designed for machine-to-machine authorization. The closest (IMO) that you can safely get while staying inside intended usage and specs is passing a SAML assertion wrapped in a WS-Trust STS transaction.
I would suggest you look into either WS-Trust or OAuth. Either of these are built for machine-to-machine transactions.
I have been looking into using an identity provider (IDP) to provide user authentication for a Windows Forms client. The user credentials will be hosted by Auth0. After creating a trial account with Auth0 I have downloaded a sample C# Windows Forms client application that can be used to authenticate to the Auth0 IDP using OpenID Connect ("OIDC"). The WinForms sample application pops up a web browser component, displays the Auth0 login screen, I login to the Auth0 IDP (having setup some test credentials in Auth0) and the WinForms application then is sent an authentication token. All well and good, and if I try to login a second time I no longer need to enter my credentials.
However... the company that I will be fetching authentication data from in production would like to use SAML. Is there any way to do this? Based on what I have read, SAML needs a "Service Provider" that will receive credentials from the IDP. The Service Provider is (typically?) a web site. That does not seem to match very well with what I am trying to do (authenticate a windows client). Is there any way of using SAML to do essentially what I have done using OIDC (fetch authentication information for a user from an IDP)? Would I need to develop a separate Service Provider component for this?
Sounds like what you've done so far is fine architecturally:
A modern desktop app following OIDC standards
This puts you in a good position architecturally, where:
Your app gets tokens from Auth0 using OIDC
Auth0 can reach out and do federated authentication with other standards based identity providers, which could be SAML, OIDC, WS-Federation or anything else
This can be done without changing any code in your app - and your app does not need to understand SAML
Feels like you need to set up a federated connection from Auth0 to the SAML Service Provider, and most commonly this involves these steps:
You give the partner your Entity Id and Response URL, to post tokens to
They give you am Entity Id, Public Key Certificate and request URL
You configure rules around account linking, so that users can be matched between their system and yours
There are prerequisites though, and the external identity provider needs to be SAML 2.0 compliant. My Federated Logins Article may help you to understand the general concepts, though I do not drill into SAML details here.
I have to use Azure Active Directory for authentication to my web application.
In my company it was suggested to use SAML instead of oauth and I am very new to SAML.
Question:
Is the purpose of SAML is only to authenticate or there is any more functionality?
There are documents to use SAML in enterprise application. So,How to implement saml from app registration?
SAML SSO is a form of delegated authentication. The user is authenticated at the identity provider site (eg Azure AD) which sends a SAML assertion containing user identity information to the service provider site. The service provider trusts this information and establishes a local authentication session for the user using the information contained in the SAML assertion. SAML assertions often contain the user's email address but any user identity information may be included. This is the primary use case for SAML and in many instances the only one supported.
Most platforms have SAML libraries etc available. It's strongly recommended you use one of these rather than trying to implement SAML yourself.
I am using a SaaS application and I want to use our own LDAP to Login to that 3rd party application. I want to provide a link to that application in my Portal. Both the applications are hosted in Cloud and are Spring based.
Please let me know where to Start and how to go about implementing SP initiated SAML.
Thanks!
First of all you need a SAML IDP that authenticates against LDAP e.g. shibboleth.
Then you need a client side SAML stack.
Refer: SAML : SAML connectivity / toolkit.
You could also look at IDaaS e.g. Auth0 or Okta.
Does Google supports SAML 2.0 Enhanced Client Proxy profile as an Identity Provider?
If so, what is the endpoint to be used to send messages?
No - they don't. For application authentication, Google's path is OAuth and OpenID Connect. See their Identity Developer page.
