How does i implement SAML SSO with Azure AD - azure

Can anyone suggest which is best idp that we can integrate with Azure AD for SAML SSO.
My goal is need to use Azure AD credentials for all my business application.
Thanks

In Azure AD, AAD is the IDP.
You are the RP.
Any SAML provider can be used e.g. ADFS, PingFederate, Shibboleth etc.
You want "Azure AD credentials for all my business application". Is your business application .NET, Java ... ? Does it have to use SAML? Could it use WS-Federation, OpenID Connect, OAuth ... ?
Is your business application one you wrote yourself or is it SaaS - many of these are already integrated with AAD.

SSO With Azure Active Directory or ADFS or AD

Newbie to Microsoft SSO Authentication.
Have metadata, pubic cert and login url and Azure AD identifier and entityid.
When I was going through this SAML2.0 i see diff types of auth strategies like Federation Services, ADFS, Active Directory, Azure Directory... Getting confused and trying to visualize the type of authentication these details support.
https://learn.microsoft.com/en-us/azure/active-directory/develop/tutorial-v2-nodejs-webapp-msal
Can somebody point me what type of authentication that we can provide with below details ?
metadata, pubic cert and login url and Azure AD identifier and entityid.

We install adfs on Windows Server operating systems. It extends on-prem identities managed within AD to cloud applications through both SAML and OAuth. AD FS is meant for on-prem environments and does not authenticate through Azure infrastructure; it only authenticates against Active Directory.
AAD mainly serves as a cloud-based user management, as well as offers SSO capabilities for web applications. In fact, it authenticates users to their applications in much the same way as AD FS. The difference is that AAD authenticates via the cloud and AD FS authenticates on-prem. 
Federation - When you set up SSO to work between multiple identity providers, it's called federation. An SSO implementation based on federation protocols improves security, reliability, end-user experiences, and implementation.
With federated single sign-on, Azure AD authenticates the user to the application by using their Azure AD account. This method is supported for SAML 2.0, WS-Federation, or OpenID Connect applications. Federated SSO is the richest mode of SSO. Use federated SSO with Azure AD when an application supports it, instead of password-based SSO and Active Directory Federation Services (AD FS).
So, if you want authenticate with cloud users you can go with azure ad or else if you want to use your on-premise user identities authenticate users for the application you can go with ADFS.
You can find more information here What is single sign-on? - Azure AD | Microsoft Docs

Azure AD for IdP and SP

Looking to deploy Single Sign-on authentication on an on-premises application (SAML integrated) with Azure AD. In real world, we have two servers a. Identity provider & b. Service provider for SSO.
However, in this case, can i use - Azure AD for IdP and also as SP (same server) for on-premise application SSO authentication? Would be great if someone please explain how would be the flow of authentication in this case?
Azure AD can be an IDP only.
It cannot function as an SP to another IDP.
Could you please elaborate on "also as SP (same server) for on-premise application SSO authentication". What do you mean here? What's the use case?
You can add custom SAML applications to AAD as per this.

How does Azure Active Directory support federation with Okta as an IDP?

Is it possible to integrate Okta as an IDP (Identity Provider) for an application in Azure, where Azure would be the Service Provider?
Presently the authentication is managed by Azure AD, we have AD users that have been granted access to these applications hosted in Azure, and Use ADAL for logging in users, and obtaining tokens for securing API calls to the Backend APIs.
Can Okta be added as an IDP and added to the AAD, through SAML or WS-Federation?
Yes, OKTA is listed as one of the third-party IDPs in the Azure AD federation compatibility list which can support federation with Azure Active Directory (AAD).
The supported scenario matrix is listed here.
Hope this clarifies your doubt.

Using Azure AD B2C and MSAL to authenticate a windows service

Is it possible to use MSAL to allow a windows service to access a web api protected by Azure AD B2C? If not, what is the best way to allow a autonomous service to access an API protected by B2C.
This scenario should be addressed with the Client Credentials OAuth flow.
This is possible in Azure AD B2C, however, the experience isn't ideal.
To do achieve this, use "App Registration" blade in the Azure Portal to register a apps that define application permissions and then register apps that use client credentials to request these. You would effectively be using the same mechanism that you use in regular Azure AD, see Azure AD's "Daemon or Server Application to Web API" documentation
Important note: Make sure you are not using the Azure AD B2C blades for this.
You can support the ask for a first class experience by voting for this entry in the Azure AD B2C feedback forum: Support OAuth 2.0 Client Credential Flow

Connecting ADFS to Windows Azure Active Directory

We are developing a multi-tenant application and would like to be listed on Azure and support Azure AD as an IdP for our customers. However, a few customers that already have ADFS 2.0 setup didn't like the idea of sync'ing all accounts and passwords to Azure AD. So, is there anyway that when Azure AD receives a login request, somehow, have it redirect to ADFS and let ADFS do all the magic and return a token back to Azure AD which then returns JWT (using OpenID Connect) to our application?
I know that ACS supports such scenario but we are worried that Microsoft would soon drop support for it.
Thanks!
