I am developing a python backend using FastAPI (in docker) and I need to:
Implement an authentication service that utilizes SSO
Search the directory for users
use identity-provider/directory-server in development that is going to be replaced eventually by Microsoft Active Directory (I am developing a mac)
I searched a lot but I am still not sure. What I know now:
I can use any directory server as long as they support ldap
through ldap, I can search the directory
However, SSO does not seem to be a feature in ldap
SSO can be implemented using SAML2
Can you please guide me how to setup this. I am not sure how to integrate SAML2 and ldap to work together in my application.

You will need to set up an identity provider (or find an existing one) that:
has support for SAML2 and can act as a SAML2 identity provider.
has support for validating user credentials using LDAP and directory servers.
Your application, acting as a SAML2 SP, would send a SAML2 authentication to this IdP. The IdP then asks the user for credentials and validates them against the directory server, and would produce a SAML2 response back to your SP. Your SP would validate and parse the response, and all things permitting, would let the user through.
An example of such an IdP would be: https://github.com/apereo/cas or https://www.shibboleth.net/products/. Both OSS under Apache v2.

I need to support 3 way of authentication at the same time in the application: LDAP, Azure AD, Basic.
After few hours of googling i found that the best way to do it would be to implement 3 authentication providers and then register them with AuthenticationManagerBuilder. But the issue i stumbled into is, that i dont know how the make the Azure Ad provider. For LDAP i found an online example i can use, and based on the LDAP i could probably also make the Basic username and password provider, but havent found anything similar on Azure AD. All i have found is that, i need to add 2-3 dependencies to the project for the Azure AD and then it automagically works.
I dont understand spring security that much, so im stumped atm. Can i just trust the automagic to do everything correctly, or are there some resouces on how to create AzureADAuthenticationProvider i could use with AuthenticationManagerBuilder?
An authentication provider is an abstraction for accessing user information from LDAP, custom third-party source, database etc. it validates the user credentials.
Spring security with azure ad:
Firstly, azure ad is integrated with Spring security for secure your application.
User login through their credential and get validate by azure AD.
From azure graph API you have to access token and membership information.
Membership for role based authorization.
LDAP Authentication:
Unique LDAP or DN ,you can perform search in directory unless you know username to DNS is known in advance.
You can authenticate the user by binding that user.
Load the Number of authorities for the user.
Custom Authentication Provider:
Create own authentication (custom) with the help of authentication provider interface in which you can use
authenticate method and implementing it and make authentication object with username and password of user
Then after you can configure these authentication in spring security configuration.
Here is the Reference Link regarding Spring Security
I’m kind of new to azure active directory. What I'm trying to achieve is:
I have a .net core application (backend api) which will be called using an angular application.
My requirement is to authenticate and enable single sign on using azure active directory.
With some time spent, I came to know that there are 2 ways to do this,
Using OpenID Connect
Using SAML
I would like to do using SAML. I tried implementing SAML SSO as follows:
I registered one application under Active directory which redirects
to my angular application. I also read that, any application we are
registering in App registrations will use OpenID by default and
there is no UI available to make it as SAML but we can do the same
using manifest.
We can register application using Enterprise applications to enable
SAML
My question is,
Is there a way we can authenticate and enable SSO in my application
registered using App registrations?
What options I should choose to enable SAML SSO while registering
enterprise application? If I select my registered application in
enterprise application it gives me the following:
The single sign-on configuration is not available for this application in the Enterprise applications experience. localhost was created using the App registrations experience.
Please go to localhost in the App registrations experience to edit properties such as reply URLs, identifiers, claims, among others. Your account should have the required permissions (Global Administrator, Cloud Application Administrator, Application Administrator, or owner of the app object).
What will be the code changes in my angular and .net core
application?
Any reference would be very helpful.
TIA
You can't do it from App Registrations but you can do it from the Enterprise Application experience. To set up SAML SSO you need to go to the application > Manage > Single Sign-On > Select SAML. The Quickstart goes through all of the steps for setting up SAML SSO from Enterprise Applications.
For Basic SAML configuration values, see Configure SAML Single Sign-On.
You can use the SAML toolkit and accompanying samples to test the SAML single sign-on integration with Azure AD
I agree with Marilee's, her answer has provided some related documents on how to create an enterprise app and how to enable SSO with the app.
What I wanna add is that I think you need to figure out which app you are willing to connect together with SSO, I mean that you just said 'an angular application', so there's only one app, how does it relate to SSO ? And if you just need to sign in both frontend app and backend app, this document may help.
Wish you could solve it soon, and if you met more questions, pls add details.
Currently we are a Service Provider (SP) which is currently using SSO Authentication using OpenAM and we are using Spring security to achieve this.
We have a login interface where user enter user name and password and authentication happens.
Now we have a requirement to allow users from an external identity provider (Azure) to access the SP in addition to the existing Open AM SSO. We are trying to use SAML 2.0 to achieve this.
For this we changed the login interface, to accept the user name and based on the user name, we either provide the password option (for local users ) or redirect to the azure portal (for idp users) to authenticate the user.
As part of this requirement, we added a variable userType into httprequest cookie and try to redirect to the respective authentication provider. But we always get redirected to azure even though the user is a local one.
We have gone through many examples from github to implement this but no luck.
Any pointers on this would really be helpful.
As far as my understanding goes, OpenID uses accounts made on other websites to sign in to the website, so that user won't have to create multiple username and password.
Does OPENAM not to do the same thing? It uses providers like Facebook google in order to authenticate the user.
Please correct me if I am wrong.
OpenID Connect is a standard.
OpenAM is a product that amongst many other things, implements the OpenID Connect standard (both as a client/relying party and as a server/provider).
So, yes, you can configure your OpenAM to work with external OpenID Connect providers to establish sessions at OpenAM, but you can just as well configure your OpenAM to perform authentication against a local directory server and act as an OpenID Connect provider (like Facebook/Google/etc).
Above you mention scenario is Single Sign On (SSO). It provide OpenID-Connect with Oauth.
OpenID is a protocol(Standard).
OpenID Connect is a simple identity layer on top of the OAuth 2.0
protocol.
OAuth only provide authorization using an access token. OpenID-Connect is built on top of OAuth2, in order to provide user authentication information.
Not only OpenID Connect whether we can used SAML(Security Assertion Markup Language) for Single Sign On.Name it
SAML SSO.
OpenAM is a product and below Link you can read OpenAM feature Wikipedia OpenAM page and additionally you can used another open source Identity Server Name WSO2 Identity Server for implement this feature and there are more additional features as well.
I have a website (azure), that has a login page for the user to insert it's username and password.
Currently, the login is using LDAP to autenticate the user.
Now the client wants to use/activate the single sign on functionality, but using their Windows Server Active Directory (they don't want to use the Azure Active Directory).
Is this possible to do? Whats the best approach?
These are the two options I know:
You can use Microsoft Active Directory Federation Services (aka ADFS). This is a component that should be installed in your customer infrastructure and talks with the AD, your website will talk WS-Federation with ADFS. Authenticating a user means basically redirecting the user to a ADFS, if the user is in the LAN and is already authenticated to AD, ADFS will login automatically, but if is outside it will prompt user credentials.
Another approach will be to use a third party authentication broker. Auth0 is an authentication broker that you can add from the azure store, you will need to create an AD "Connection", which will require to install an small MSI on your customer infrastructure. For this case it works more or less like ADFS but your application talks OAuth with Auth0 rather than Ws-Federation so in lot of cases it is easier to implement.
Disclaimer: I work for Auth0.
