Snowflake AAD OAuth2 (EXTERNAL_OAUTH_JWS_CANT_RETRIEVE_PUBLIC_KEY) - oauth-2.0

We've configured Snowflake for Oauth2 using AAD when we retrieve a token the audience, scope, ... are correct.
But when validating using SYSTEM$VERIFY_EXTERNAL_OAUTH_TOKEN
we receive the following error (and no information can be found why this is occuring)
Token Validation finished.{"Validation Result":"Failed","Failure
Reason":"EXTERNAL_OAUTH_JWS_CANT_RETRIEVE_PUBLIC_KEY"}
Has anyone had this error before?

Most likely while creating the security integration,value for Public Key was not extracted from the IdP's certificate and instead, the certificate was entered.

AADSTS50146 error when attempting to retrieve Oauth access_token

Looking for some AzureAD help with this error -
"error": "invalid_request", "error_description": "AADSTS50146: This
application is required to be configured with an application-specific
signing key.\r\nTrace ID:

I get the error above in one AzureAD env. when trying to do a OAuth2.0 token request. I have another test AzureAD where the same request works fine.
Doing a POST to https://login.microsoftonline.com/{tenantId}/oauth2/v2.0/token with clientId, clientSecret and grant_type=client_credentials.
Found this via google - https://github.com/MicrosoftDocs/azure-docs/issues/5394 but wanted to understand how does one go about configuring the "scope" parameter in AzureAD.
You probably have additional/mapped claims.
If you do not want to bother with creating application-specific signing keys,
you need to set "acceptMappedClaims": true in the manifest.
Setting "accessTokenAcceptedVersion": 2 can also help.
The api permissions in Azure AD portal is the value of scope.
You can also expose an API, then you can add your own scope.

Config ADFS / Spring Security to accept unsigned SAML AuthnRequest

I'm trying to get my web app SAML-integrated with ADFS (it already works with other IdPs). The AuthnRequest that's sent to ADFS is unsigned. ADFS rejects the request, leaving this message in its log:
Microsoft.IdentityModel.Protocols.XmlSignature.SignatureVerificationFailedException: MSIS0037: No signature verification certificate found for issuer 'com.onshape.saml2.sp'.
I've tried doing:
Set-AdfsRelyingPartyTrust -SignedSamlRequestsRequired $False
but that didn't help.
Can I configure ADFS to accept my app's unsigned requests? Or make some change to my app to make it generate requests that ADFS will accept?
The error message is a bit misleading - the usual root cause is a mismatch between the issuer in your authentication request (com.onshape.saml2.sp) and the entity ID of the service provider you registered with ADFS.

Spring Boot + Security OAuth2.0 Client with Custom Provider

I am creating a OAuth2.0 client for a custom OAuth2 provider in Spring Boot + Security (version 5) application.
Below is the application.properties which has all the configuration and there is no additional configuration class in my project.
spring.security.oauth2.client.registration.xxxxxxxxx.client-id=XXXXXXXXXX
spring.security.oauth2.client.registration.xxxxxxxxx.client-secret=XXXXXXXXXX
spring.security.oauth2.client.registration.xxxxxxxxx.scope=openid
spring.security.oauth2.client.registration.xxxxxxxxx.redirect-uri-template=http://localhost:8080/login/oauth2/code/xxxxxxxxx
spring.security.oauth2.client.registration.xxxxxxxxx.client-name=xxxxxxxxx
spring.security.oauth2.client.registration.xxxxxxxxx.provider=xxxxxxxxx
spring.security.oauth2.client.registration.xxxxxxxxx.client-authentication-method=basic
spring.security.oauth2.client.registration.xxxxxxxxx.authorization-grant-type=authorization_code
spring.security.oauth2.client.provider.xxxxxxxxx.authorization-uri=https://api.xxxxxxxxx.com/authorize
spring.security.oauth2.client.provider.xxxxxxxxx.token-uri=https://api.xxxxxxxxx.com/token
spring.security.oauth2.client.provider.xxxxxxxxx.user-info-uri=https://api.xxxxxxxxx.com/userinfo?schema=openid
spring.security.oauth2.client.provider.xxxxxxxxx.user-name-attribute=name
spring.security.oauth2.client.provider.xxxxxxxxx.user-info-authentication-method=header
When i hit http://localhost:8080/ it redirects properly to provider's login page and after successful login it redirects back to my application.
Now the problem is when it redirects then it shows below error message.
I have googled for this error but didn't get any proper answer. Also, the OAuth2 provider didn't share such URL.
After research I came to know that i need to set below property. Should it be provided by Auth Provider?
spring.security.oauth2.client.provider.pepstores.jwk-set-uri
What exactly I am missing here in configuration?
Finally, the problem is solved. I just need to configure the jwk URI which should be provided by the Auth provider.
Below the final configuration for customer Auth Provider.
spring.security.oauth2.client.registration.xxxxxxxxx.client-id=XXXXXXXXXX
spring.security.oauth2.client.registration.xxxxxxxxx.client-secret=XXXXXXXXXX
spring.security.oauth2.client.registration.xxxxxxxxx.scope=openid
spring.security.oauth2.client.registration.xxxxxxxxx.redirect-uri-template=http://localhost:8080/login/oauth2/code/xxxxxxxxx

Thanks
When you receive JWT in client application, you need to verify the signature of JWT. To verify the signature you need public key of Auth provider. As per OAuth specifications, Auth provider can expose the public key through a URI and client can use this URI to get the public key to validate the JWT. This is what is missing in your configuration.

'Insufficient Privileges' error while using 'addKey' action in Azure AD Graph API

I have an application registered in Azure AD which uses certificates. I am trying to write a script which would add a new certificate to the application. This can be used to add a new certificate when the existing certificate is going to expire.
I am trying to use AddKey function of Azure AD Graph API. The request body of this api as a parameter 'proof' which is a JWT assertion signed by the existing certificate of the application. The doc says the "aud" claim in JWT should be set to "AAD Graph SPN". Here what is meant by "AAD Graph SPN"?
I tried with a JWT where "aud" was set to "00000002-0000-0000-c000-000000000000". But I am getting the following error,
{
"odata.error": {
"code":"Authorization_RequestDenied",
"message":{
"lang":"en",
"value":"Insufficient privileges to complete the operation."
}
}
}
Any thoughts on this?
I am getting the access token to call the Azure AD Graph API via "Resource Owner Credentials Grant" flow . To get the access token i am using the client_id "1950a258-227b-4e31-a9cf-717495945fc2" (The Well Known Client ID for Azure PowerShell")
My script (For deployment purpose) does something like below,
i) Get the access token as described above and registers a new application in Azure AD with a initial certificate.
ii) When the initial certificate is about to expire it should add a new certificate to the created application.
According to the documentation, you must use a self-signed JWT token to access that API:
As part of the request validation for this service action, a proof of
possession of an existing key is verified before the action can be
performed. The proof is represented by a self-signed JWT token. The
requesting application needs to generate a self-signed JWT token with
the following requirements...
The "Resource Owner Credentials Grant" won't work here in this situation. Instead, use the "Client Credentials Grant":
https://learn.microsoft.com/en-us/azure/active-directory/develop/active-directory-protocols-oauth-service-to-service
The application you want to update should be the Client ID used to get this access token.
The other option is to update the application directly using an PATCH request on the Application Object:
https://msdn.microsoft.com/en-us/library/azure/ad/graph/api/entity-and-complex-type-reference#application-entity
Using this method, you should be able to update using the method you described above (user credentials and an external Client ID)
Let me know if this helps.

Spring Security and Google OpenID Connect migration

Questions:
1) What's the best way to integrate OpenID Connect authentication into a webapp that uses Spring Security for authentication?
2) Is there any way - either from the MITREid side of things or the Google Accounts side of things - to get the MITREid OpenID Connect authentication filter to work with Google's OpenID Connect service?
I'm sure answers to these questions will be useful for any developer that uses the Spring Security OpenID module to authenticate with Google.
Detail:
My webapp uses Spring Security's OpenID module (<openid-login .../>) for authentication with Google Accounts as the Identity Provider. ie., users authenticate using their Google Apps or GMail email address.
Recently, whenever users authenticate, they receive this warning message from Google accounts:
Important notice: OpenID2 for Google accounts is going away on April
20, 2015.
So Google is dropping support for OpenID, will turn it off completely in April 2015, and states that you must switch to the OpenID Connect protocol if you want to authenticate with Google Accounts.
I was hoping Spring Security would have built-in support for OpenID Connect, just like it has built-in support for OpenID. e.g. something like an <openid-connect-login .../> element. But my searches have turned up no such support.
The best candidate I've found so far is MITREid Connect . It includes a Spring Security authentication filter named OIDCAuthenticationFilter for OpenID Connect. The problem is, it does not interoperate with Google's OpenID Connect implementation.
I tried cloning the MITREid simple-web-app and configured it to authenticate (using OpenID Connect) with Google Accounts. But it did not work because it depends on a nonce which Google's OpenID Connect implementation does not support. The error message from Google accounts was:
Parameter not allowed for this message type: nonce
Next I tried plugging my own implementation of MITREid's AuthRequestUrlBuilder interface into the MITREid configuration. The only difference between my implementation and MITREid's implementation was that I did not send the nonce.
Not sending the nonce made Google's OpenID Connect implementation happy but MITREid threw an exception when it couldn't find a nonce in the Google authentication response. The error message was:
Authentication Failed: ID token did not contain a nonce claim
I tracked the MITREid exception down to these lines in MITREID'S OIDCAuthenticationFilter:
// compare the nonce to our stored claim
String nonce = idClaims.getStringClaim("nonce");
if (Strings.isNullOrEmpty(nonce)) {
logger.error("ID token did not contain a nonce claim.");
throw new AuthenticationServiceException("ID token did not contain a nonce claim.");
}
But there is no way for me to extend MITREid's implementation to ignore the nonce. So close but yet so far! If Google Accounts would accept the nonce or MITREid could be configured to ignore the nonce then we'd have a solution.
Within the MITREid Connect issues list on github I've found others have run into these similar issues:
1) #726 - Documentation on using client with Google as authentication provider
2) #704 - Add a useNonce attribute into ServerConfiguration to indicate if the IdP accepts the nonce value into its requests.
So I am stuck. Come April 2015 Google will shutdown Open ID authentication.

2015-02-18 Update
Functionality has recently been added to the development branch of mitreid-connect for disabling the nonce - therefore making Google's OIDC server happy. Thankfully, mitreid-connect has also provided some guidance on interoperating with Google .
Unfortunately the "nonceEnabled" change is not yet available in Maven central but hopefully that will change soon.
AFAIK, there is no clean and easy Spring Security migration from OpenID to OpenID Connect authentication. Implementing OpenID authentication with Spring Security is straight-forward using the well documented <openid-login/> but there exists no analog for OpenID Connect.
The MITREid alternative is still on a development branch and unavailable at Maven Central and therefore not a candidate.
In the comments, Chuck Mah points to How to implement Openid connect and Spring Security where Romain F. provides the sample code.
Romain's sample code pointed me in the right direction. Given time is running out, I went with romain's approach, which was to write a custom Spring Security AuthenticationFilter that uses spring-security-oauth2 to query the oauth2 api userinfo endpoint (for Google that's https://www.googleapis.com/oauth2/v2/userinfo). The assumption is that if we are able to successfully query the userinfo endpoint then the user has successfully authenticated so we can trust the information returned - eg the user's email address.
When i first started learning about OpenID Connect the “id token” seemed to be the central concept. However, browsing the spring-security-oauth2 source code, it appears to be ignored. This leads to the question, what’s the point of the ID token if we can authenticate without it (by simply querying oauth2 userinfo endpoint)?
A minimalist solution - which i would prefer - would simply return a validated ID token. There would be no need to query the userinfo endpoint. But no such solution exists in the form of a Spring Security authentication filter.
My webapp was not a spring-boot app like romain's. spring-boot does alot of configuration behind the scenes. Here are some of the problems/solutions I encountered along the way:
problem: HTTP Status 403 - Expected CSRF token not found. Has your session expired?
solution: java config: httpSecurity.csrf().disable()
problem: HTTP Status 500 - Error creating bean with name 'scopedTarget.googleOAuth2RestTemplate': Scope 'session' is not active for the current thread;
solution: java config: OAuth2RestTemplate does not need to be session scoped (OAuth2ClientContext is already session scoped and that's all that's necessary)
problem: HTTP Status 500 - Error creating bean with name 'scopedTarget.oauth2ClientContext': Scope 'session' is not active for the current thread;
solution: web.xml: add RequestContextListener
explanation: because the oauth2ClientContext session-scoped bean is accessed outside the scope of the Spring MVC DispatcherServlet (it is being accessed from OpenIdConnectAuthenticationFilter, which is part of the Spring Security filter chain).
<listener>
<listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
</listener>
problem: org.springframework.security.oauth2.client.resource.UserRedirectRequiredException: A redirect is required to get the users approval.
solution: web.xml: Add filter definition immediately PRECEEDING springSecurityFilterChain
<filter>
<filter-name>oauth2ClientContextFilter</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>
<filter-mapping>
<filter-name>oauth2ClientContextFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
Unfortunately, OpenID Connect does not allow us to request only email scope.
When our users authenticated using OpenID they would see a consent screen like "webapp would like to view your email address" with which they were comfortable. Now we must request scopes openid email resulting in a consent screen asking the user to share their entire public profile with us ... which we really don't need or want ... and users are less comfortable with this consent screen.
