We are looking to implement SAML based IDP(with signed response & encrypted assertion) in Azure and our SP will be some another service. For this, we need to configure our SP public cert at IDP side in Azure. We have created basic IDP with "Azure Active Directory>>Enterprise applications>>Non-gallery application". So now we need to know, how we can configure SP public cert at IDP in Azure?
You don't have to configure your SP public cert in Azure AD. Azure AD will ignore the signature in the SAML request. The only thing you need to configure in Azure AD is Identifier, Reply URL and add any custom attribute expected in the SAML response. Then, use the metadata or certificate to configure SSO on the SP.
Take a look at these docs:
Azure AD Single Sign-On SAML protocol
In case you want to list your application in the AAD Gallery for allowing common customers to add and configure your application: Listing your application in the Azure Active Directory application gallery
Signed Response
Azure AD has an option for signing its SAML Responses. Just make sure you download Azure's metadata to grab the Azure's signing certificate.
Encrypted Response
Azure AD calls encrypting the assertions inside the SAML Response, to be Encrypted Tokens which is really not a very good name at all. It is also unfortunately not with the rest of the SAML options. This page explains how to do it. You will need to have your SP enc cert in a PEM format. The rest should be simple.

We are working on SAML-based SSO with Azure AD.
WE did all the required setup and able to make the SAMLRequest and able to get SAMLResponse on reply URL. But the response is BASE64 encoded and encrypted.
I am not able to decode the response as it required idpPublicKey, spPublicKey & spPrivateKey.
Can someone help how to generate these keys and configure in AZURE AD.
(1) Manage certificates for federated single sign-on in Azure Active Directory (on the official Microsoft website) provides the instruction on how to generate idpPublicKey of Azure AD and configure SSO with Azure AD.
(2) spPublicKey & spPrivateKey should be generated by your SAML SP application (NOT by Azure AD IdP), for example, Shibboleth SAML SP at GitHub repository provides a sample for spPublicKey & spPrivateKey and SAML SP configuration example under "shibboleth-sp-testapp/shibboleth-sp/".
Another StackOverflow question Keytool - Generate Public key in X.509 format using existing private key provides the instruction how to use native OpenSSL command to generate spPublicKey & spPrivateKey for a SAML SP application.
You just required idpPublicKey inorder to validate the SAML response. Azure AD does not validate the SP requests.
So you do not required any SP public/private keys.
I'm adding SSO feature to my service to allow customers login with their AD accounts. To provide this I use SAML component from componentpro.com
What is correct way to perform security interaction:
From IdP side: what should customer provide to my service besides IdP url? Any certificate that just contains public key?
From SP side: what should I provide to customer?
Choosen SAML tool uses certificates to sign SAML request to IdP and to decrypt assertion from IdP. What are that certificates (from previous questions)? Is it the same certificate for signing and decrypting?
Update: useful link about using certificates in SAML communication.
Normaly this is set up using a SAML metadata file that contains the IDP endpoints, keys etc. Your service then sends a similar metadata file with information about your service to the IDP
If the customer is the IDP then as above you usually provide them with a metadata file.
It is gennerally a bad idea to use the same key for signing and encryption. Read the discussions here and here
I want to use Azure as an identity provider for a third party service provider(SP). My question is
How can I generate the client ID and Client secret with respect to the SP. (Please note that my SP is not an application, but another IDP which will be an SP to Azure since the scenario I'm try out is Multi Factor Authentication )
webapp ----> Third party IDP(Acts as a SP to Azure) ------> Windows Azure
How can I get the public key of Azure?
Any help appreciated.
If all you desire is to signin a Azure AD user to your web app, you don't need OAuth: you need to configure web single-signon between your web app and the intermediate IdP and between the intermediate IdP and Azure AD. At your app, the user's browser will be redirected to the intermediate IdP and then to Azure AD. The user will authenticate at Azure AD. You can turn on MFA for the user in Azure AD - this will be enforced at authentication. Post successful auth,an authentication response will be sent back to the intermediate IdP and it will send an authentication response to your web app. For Web SSO you can either use SAML or WSFed (depending on what your intermediate IdP supports.)
You will need to configure your intermediate IdP as an SP in Azure AD. If you haven't already, signup for Azure. Signin to the management portal, and go the Active Directory tab on the left. Select the directory and go to the applications tab. This is where you should register a new app representing the SP (your intermediate IdP). The following properties of the app are important:
App ID URI: this should match the Issuer of the SSO request that your intermediate IdP sends to Azure AD
Reply URL: this is the URL where Azure AD will post the authentication response. Your intermediate IdP should listen for authentication responses at this URL.
Next you will need to configure Azure AD as an IdP in your intermediate IdP. All the data required to configure this is in Azure AD's federation metadata document. While on the configure application page in Azure management portal, click on the View Endpoints button in the bottom bar to get the Federation Metadata Document URL of your Azure AD (https://login.windows.net/{tenant_id}/federationmetadata/2007-06/federationmetadata.xml).
If you do indeed need to use OAuth with Azure AD: on the application configuration page you will find the Client ID of the app (a Guid value). You can generate a key (valid for 1 or 2 years) - this will serve as the Client Secret.

I need my mobile application to allow authenticating either to 3rd party vendor (facebook, google, etc) or to my own WS-Federation identity provider (I'm using Thinktecture). Now, when logging in to my own WS-Fed idp I want to authenticate directly and pass the security token to Azure ACS (and not by using a dedicated login page). I need that because I don't want my users to authenticate using my provider by using a dedicated web page (and moving out of the context of the application).
Your help will be appreciated.
From your ACS management portal get list of identity providers of your realm from below link
https://YourNamespace.accesscontrol.windows.net/v2/metadata/IdentityProviders.js?
protocol=wsfederation&
realm=YourAppRealm&
reply_to=YourAppReturnURL&
version=1.0
Now try this:-
HTTP GET on the above identity providers link.
Parse login link of desired identity provider from the json response of above request.
Authenticate user with login link received in last step.
You'll receive your ACS Token
Note:
After step 3 user will be asked to authenticate himself and the identity provider will automatically send the authentication token to ACS, finally ACS will convert that token into new ACS token and return it as in step 4.
In this way you'll by-pass the login page and can grab ACS token in mobile application without moving out of the context of the application.
I am exposing a WCF Data Services hosted on IIS through Service Bus Relay using webHttpRelayBinding. While I could find out how to authenticate the service identity using username/password or shared secret. However, I could not find a sample how to use a certificate based credential for the service identity. I googled a lot, but in vain. All of them are based on shared secret primarily.
Could anyone please provide a sample on how to use the certificate based authentication of service identity for a REST OData service.
Currently, there are four options for authentication (according to the Service Bus docs):
•SharedSecret, a slightly more complex but easy-to-use form of
username/password authentication.
•Saml, which can be used to interact with SAML 2.0 authentication
systems.
•SimpleWebToken, which uses the OAuth Web Resource Authorization
Protocol (WRAP)and Simple Web Tokens (SWT).
•Unauthenticated, which enables interaction with the service endpoint
without any authentication behavior.
It does not look like you are able to authenticate using a certificate through Service Bus natively.
