I have got the following Article from Microsoft
For the Windows Server Technical Preview, the AD FS server role includes the same functionality and feature set that is available in Windows Server 2012 and Windows Server 2012 R2. It also includes new features that enable you to configure AD FS to authenticate users stored in non-AD directories, such as X.500 compliant Lightweight Directory Access Protocol (LDAP) directories and SQL databases. In many organizations, identity management solutions consist of a combination of Active Directory, AD LDS and third-party LDAP directories, as well as SQL databases. With the AD FS support of the non-AD identity stores, you can benefit from the entire enterprise-ready AD FS feature set regardless of where your user identities are stored. For more information, see Configure AD FS to authenticate users stored in LDAP directories
My question is how can I create custom authentication stores in SQL DB?
You are asking about ADFS 3.0 but the quote refers to ADFS vNext?
If the question is "Does ADFS3.0 provide custom authentication stores in SQL DB", the answer in No.
ADFS 3.0 only authenticates against AD.

What we are trying to do is set up our MVC .NET application with Azure Connected Services within Visual Studio. We are trying to connect to the Existing Azure AD Application. We have the correct domain selected, and also the correct redirect URI
We need to be able to read directory data to determine user group but we don’t have client secret
This is the error we get
Make sure your existing Azure AD application is registered as:
Accounts in this organizational directory only (Devchat only - Single tenant) or Accounts in any organizational directory (Any Azure AD directory - Multitenant).
Other types are not supported to be updated in this case.
You can refer to this document to register an application for a quick test.
We have an application which is hosted on the on-premises Windows server (IIS) server
now I created a windows server on azure and building a web app for it.where the application needs to authenticate the user by windows server (DC) using kerbrose protocol but I couldn't find any documentation regarding this from Microsoft's side
Is the above query possible to be implemented in the azure web app?
No, it's not possible. Windows Authentication is something for on-premise deployments. For Azure Web Sites Azure Active Directory is clearly the best option. Sync from AD to Azure Active Directory is also quite easy to setup.
If you still want to absolutely use Windows Auth and host your website on Azure, you can create Windows VM and host your website there. You then need to join the VM to your AD. To this, both VMs must be in the same network. So if your VM is on-premise you will need to create an site-to-site VPN.
For more information, follow this SO which also discussed about this.
If your intention is to join the VM hosting the website to a domain then as others have mentioned, this isn't possible.
However, doing Kerberos authentication itself within an Azure website isn't particularly difficult, but it does require manual implementation. Windows natively handles all of this for you on domain joined machines and and IIS exposes that functionality. Since you can't domain join you have to manually do all that heavy lifting and request and validate the tickets yourself.
This involves creating a service account in Active Directory and keeping the account password in sync. Once you have that you need to indicate to the browser that it needs to negotiate auth, which is done with the WWW-Authenticate: negotiate header on a 401 response. The client, if configured to send tickets, will send a ticket in the Authorization: Negotiate YII... request header on a subsequent response. At this point you need to shove that negotiate header and that original service account password into something that can validate Kerberos tickets. Windows SSPI will do this for you, but it's a pain. I built a library that'll do this for you: Kerberos.NET. YMMV with what works best for you.
All of that said, it may be more beneficial to switch over to a more modern authentication mechanism like OAuth/OpenIDConnect/SAML.
There are several ways depending on if you have to allow access to users who are associated with a on-premise Active Directory or not.
You should have a look at this service: https://learn.microsoft.com/en-us/azure/active-directory-domain-services/
It will offer an Active Directory within Azure where you can domain join your VM to and then using Kerberos as authentication protocol (should work the same way like on prem).
The other option would be to create a new Active Directory within your Virtual Network (via 1 or 2 small Windows Server VMs where you create the AD).
The good thing if you are using Active Directory Domain Services would be that you could extend it to your on-prem Active Directory by synchronizing or federating your on-prem AD.
There are more informations regarding these scenarios here:
https://learn.microsoft.com/en-us/azure/active-directory/hybrid/whatis-hybrid-identity
For a Azure App Service - Web App you would connect it to your Azure Active Directory (AAD) and use the hybrid identity model to allow users who originate from an on-prem AD access to it:
https://learn.microsoft.com/en-us/azure/app-service/configure-authentication-provider-aad
Hope this helps a bit, it is a rather complicated topic you are digging into.
We are in the planning phase of configuring our soon-to-be-upgraded databases (19c) to authenticate directly against AD (no oracle proxy). I have read a handful of documents from Oracle on how to do this. Most of the documentation focuses around using passwords (password filter/verifier). The only problem is that our AD administrators are dead-set against implementing Oracle's password filter into our existing AD infrastructure. That being said, one of the security guys said we could implement the oracle authentication using Kerberos instead. From what I have read, and the documents are scattered all over the place, and nothing that detailed, to use Kerberos:
1) The client no longer uses a username/password - they connect using a wallet-style connection (e.g. /#dbname)
2) Not only does the Oracle DB need some configuration changes, but so does every client that plans on using Kerberos
I don't know anything about Kerberos, how it works, and what goes on when you implement this, but I was hoping for, at the end of this is:
1) No client changes/installs (only the oracle DB would have config changes)
The user will continue to provide credentials as before - completely transparent
2) No need for the password filter as our admins have a "beef" against it
So my question is:
If using Kerberos directly against AD on >=18c:
1) Does the client user still provide a username and password to authenticate against AD, or does the client simply get "accepted" due to the tickets/tokens/configuration that occurs on the client (i.e. the client is simply trusted)?
2) Is there client config changes that need to occur, or does the client reach out to the DB and the DB, with its config changes, does all the legwork to authenticate against AD based off of client info being passed
3) Does any additional manual component need to occur on occasion (periodically retrieving a ticket/token/something) (because, say, it expires)
So in the end, we want to have complete transparency with every client and using something other than the password verifier with AD.
Thanks in advance.

It sounds like you want to authenticate Windows clients against an Oracle database over a network using Active Directory without making any client changes.
This is pretty open-ended and complex StackOverflow question.
Probably you've been reading the docs about Third Party Network Authentication using Oracle Advanced Security. You can use Kerberos, SSL, RADIUS, PKI, etc. For most of these options, you need to do some setup on the client, because both the Oracle client and server need to authenticate or verify with the third-party system.
I think you need Enterprise User Security (using Oracle Internet Directory). Assuming you go with password-based authentication, you don't need client changes. In this scenario, Oracle Internet Directory can synchronize its user directory with AD, so your users can use their same username/password. However, when they change their AD password, they'll need to change their Oracle password separately.
On a different note, you may be able to alleviate your AD admins' fears about Oracle password complexity requirements, since you can change or remove those to fit your AD requirements.
can someone please tell the difference between Oracle Internet Directory and Oracle Access Manager?
For Single sign on configuration do we need both?
thanks

yes both needs to be present.
Oracle Internet Directory is LDAP Server. OID (Oracle Internet Directory ) from OAM perspective contains the user's data. OAM uses OID as user identity store. But OID is not mandatory, any other LDAP server can be used like AD, DSEE, OVD, OUD.
OAM provides authentication, authorization, single sign on and session management service for web applications (It also supports same for non-web based application).

I'm in the process of rearranging our web-based systems, so that users will be able to log on to our systems through a Sharepoint front-end. Our single sign-on server is an Oracle SSO server that authenticates against the same domain as the sharepoint server does, but these two are currently 2 separate logins.
What I'm looking for is to configure this scenario:
A user logs in to the Sharepoint site, authenticating agains Active Directory through the TMG. This gives the user access to the sharepoint site, and this is all standard OOTB functionality. Then the user should be able to navigate into our other systems without a re-login (because the SSO configured for external authentication with the same AD, and therefore uses the same userbase).
So basically the users currently have to login twice with the same domain\user + password. I would like the SSO server to be able to read the cookie that was established in the first login, and use that instead of presenting the SSO login screen all over again.
Is it possible to share such a cookie between 2 different platforms on the same domain?
I have implemented a kerberos "Zero-sign-on" approach for the Oracle SSO server, but this only works as long as the user comes from a computer inside our domain. When the user logs on from the outside world (www) he will be prompted to login to sharepoint first, and then to the Oracle SSO.
I basically need the Oracle SSO Cookie to somehow read the Sharepoint Cookie that was established. Does this make sense?
