#OAuth2

I want to integrate IRIS with Keycloak OAuth2 provider to use delegated authentication everywhere and to secure everything - sys*/Portal applications, REST services, FHIR server and so on. If an unathenticated user tries to access any IRIS URL - he or she should be redirected to Keycloak. After the user has successfully authenticated, i would like to access his requistes (username, email, roles, scopes) extracted from the JWT token, programmatically. What should be done to achieve that?

I finally figured out how to get JWT token using set x = ##class(%SYS.OAuth2.Authorization).GetAccessTokenClient("medbank","openid fhirUser",.prop,.err).

I also found iris-fhir-client app on Open Exchange. I registered Epic sandbox server, but I cannot list resources. I suspect I need to integrate authorization / authentication. How do I do this with irisfhirclient py?

Working on a project where I'm needing to make FHIR calls from my HealthConnect Interop production to Epic. 

My issue is I'm not able to construct a valid JWT for the OAuth token retrieval that Epic will accept. I have the below code where I'm able to create a valid header and payload that I'm base64URL encoding and then trying to sign with my .pem private key file. However, Epic is not liking the signature portion of my JWT.

As such, I wanted to present my code to see if I'm performing the signature steps correctly? I've seen some posts where the %Net.

I need to create a JWT to connect to EPIC FHIRserver sandbox.

https://fhir.epic.com/Documentation?docId=oauth2&section=BackendOAuth2G…

You will generate a one-time use JSON Web Token (JWT) to authenticate your app to the authorization server and obtain an access token that can be used to authenticate your app's web service calls. There are several libraries for creating JWTs. See jwt.io for some examples.

The header and payload are then base64 URL encoded, combined with a period separating them, and cryptographically signed using the private key to generate a signature.

I have just learned about configuration merge. However I see there is no option to configure OAuth2 with CPF. Any hopes to get that covered some day?

Hi

I'm trying to use JWT authentication on a REST application in IRIS. The login API are correctly "injected" into the application. Login works fine with Postman and other REST clients, and subsequent calls to my REST API using the bearer token work fine (correctly authenticated). So far, so good.

The problem is that it doesn't work with Axios, so I can only test it, I cannot integrate it into my application.

I'm trying to authorise my app using OAuth 2.0 i Cache. Sadly I'm unable to exchange the authorization code for an access token.

I am able to redirect user to the /authorize page, where the user can login and approve my app. The user is then correctly redirected back to my app and a ?code parameter is sent back.

I am trying to use IRIS for Health as a Facade for an external FHIR Server, where IRIS provides the proper authentication. The client authenticates using a bearer token obtained from the IRIS OAuth2 server via a jwt client assertion. The IRIS endpoint, however, returns a 401 as soon as I remove the Unauthenticated access

Is there w way to make this work through configuration?

In the last article we presented the architecture of our SMART On FHIR project, so it's time to get down to business and start configuring all the elements that we are going to need.

We will first start with Auth0.

AUTH0 configuration

We will start by creating an Auth0 account with a valid email, once registered we will have to create our first application, and we will do it from the menu on the left:

In our example, the application will be of the Single Page Web Application type as it is an application developed in Angular 16. We select this option and click Create.

Dear All,

I am currently part of a team that is developing an application using Microsoft PowerApps as the front end and IRIS as the backend.  Effectively that frontend screens, which are house and an Azure serve, call a series of REST interfaces exposed by IRIS from a physical Microsoft server.  During the development stage we have not had any security in place but now we need to secure the application using a single sign on.  PowerApps relies on Microsoft Entra for its security both LDAP and OAuth.  Has anyone in the community connected IRIS to Microsoft Entra?

Question for folks who have connected to an External FHIR repository outside of IRIS. Within the HS.FHIRServer.Interop.HTTPOperation there is not an option to include TLS or an OAuth authentication when connecting to an external Repository. So then how is that piece done if you need to Authenticate against an OAuth Server before you are able to access the data or call the Web Services/REST calls?

Hello,

I have my server setup a resource server.  When a user calls our API they submit a bearer token as authorization and in our dispatch class AccessCheck() we validate the JWT using ##class(%SYS.OAuth2.Validation).ValidateJWT(). 

If I include a scope to check in that method I get the error Scope check may only be done on requesting client and I'm not sure what this means. The method works without include the scope and will let me know if I have an unsigned token or an expired token.  

I noticed that the implementation of the method calls Set token=##class(OAuth2.AccessToken).

Say I've been developing a web application that uses IRIS as the back end. I've been working on it with unauthenticated access. It's getting to the point where I would like to deploy it to users, but first I need to add authentication. Rather than using the default IRIS password authentication, I'd like users to sign in with my organization's Single Sign On, or some other popular identity provider like Google or GitHub. I've read that OpenID Connect is a common authentication standard, and it's supported by IRIS. What is the simplest way to get up and running?

The objective of the article is to provide the reader with the following informations:

• Configure and use the FHIR server
• Create an OAuth2 Authorization Server
• Bind the FHIR server to the OAuth2 Authorization Server for support of SMART on FHIR
• Use the interoperability capabilities of IRIS for Health to filter FHIR resources
• Create a custom operation on the FHIR server

Schema of the article:

We conclude this series of SMART On FHIR articles with Auth0 and InterSystems IRIS FHIR Repository by reviewing our application developed in Angular 16.

Let's remember what the architecture defined for our solution is like:

Our front-end application corresponds to the second column and as you can see it will be in charge of two things:

1. Redirect the login request to Auth0 and receive the response.
2. Send and receive the response of requests via REST sent to the FHIR server.

Introduction

I recently participated in a fantastically organized hands-on by @Patrick Jamieson in which an Angular application was configured together with an IRIS FHIR server following the protocols defined by SMART On FHIR and I found it really interesting, so I decided to develop my own Angular application and thus take advantage of what I learned to publish it in the Community.

SMART On FHIR

Let's see what Google tells us about SMART On FHIR:

SMART on FHIR is a data standard that allows applications to access information in electronic health record (EHR) systems.

Good afternoon! 👋 We would be very grateful if you are kind enough to read and respond to our request 😊.

We need given an Authentication request issued towards our OAuth 2.0 authorization server; that in case of error, the responded message is customized.

Currently if we point from POSTMAN to:
https://[IP]:[Port]/oauth2/token?grant_type=client_credentials&scope=my/scope

Username: Erroneous
Password: Erroneous

We get:
{
    "error": "server_error",
    "error_description": "ERROR #5002: Cache error: <INVALID OREF>zAuthorize+28^OAuth2.Server.Token.

Is it possible to authenticate an xDBC (ODBC/JDBC) connection to InterSystems IRIS via (a 3rd party) OAuth server?

For REST APIs this is possible, but could this be achieved with OAuth? 

Out-of-the-box the ODBC/JDBC Drivers don't seem to have this option, but maybe some custom code could enable this? perhaps via Delegated Authentication and some OAuth classes customization, or some other way?

Has anyone done this already and can share how it was implemented, or someone with some guideline suggestions?

Hello,

I have created a service in Node.js which interacts with IRIS using APIs. The current implementation uses basic auth. I want to implement OAuth 2, to make the communication between the node.js service and IRIS secure. I want my service to act as client and IRIS as Authorization and Resource server. I don't know how to do that. Anyone who has implemented OAuth using IRIS can you help me out or point me in the right direction on about how to implement it? 

Thank you for your help :)

I am attempting to setup my first OAuth2 client, as we are adventuring into the realm of making FHIR API calls to our EMR from HealthShare Health Connect. 

I have gone through and set up the Issuer Endpoint, and Client Configuration but now I want to test it and verify that the setup is correct. When I setup the Client Configuration, it would not allow me to use Discovery as it was saying I needed a "Client secret" but was not given one. So I set it up manually, thinking I hit all the information correctly.

Trying to setup my first OAuth 2 client to authenticate against Epic's Interconnect instance that is hosting FHIR/Web Service API's. Epic's documentation says the JWT request has to be sent as a POST request..

Does 

GetAuthorizationCodeEndpoint

and 

GetImplicitEndpoint

automatically put the request into a POST request, or do I need to format a %Net.HttpRequest to POST?

Thanks

Scott

Hi,

I use Caché COS and I'm having trouble doing a POP3 on the Microsoft email server using OAuth 2.0 authentication.

I'm using the following program to accomplish this task:

QGPOP ; Recebe e-mail da Microsoft Office 365
  Set server=##class(%Net.POP3).%New()
  Set server.port=995
  Set server.StoreAttachToFile=1
  Set server.AttachDir="D:\HOME\CNTIRET"
  Set servername="outlook.office365.com"
  Set user="importacao@ferrolene.com.br",pass="xxxxxx"
  Set AccessToken="exxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
  set server.SSLConfiguration="Transnovag"
  Set status=server.

In this article I will explain how to Authenticate, Authorize and Audit by code by using CSP Web Application along with Enabling /Disabling and Authenticate/Unauthenticate any Web Application.

Hello,

I am trying to get FHIR Resource using OAuth 2.0 . I get access_token sucessfully but when I use this token i get this type of error in postman. It is showing 401 Unauthorized please suggest any solution.

Thank You  

I have been testing FHIR and Iris OAuth2 but have noticed that my callback (redirect uri) I have configured in the Client config, gets called multiple times with the same code.

Has anyone else experienced this issue?

Any help would be appreciated 

I am in need of a routine or class method to generate an Oauth 1.0 signature.  I was about to code this myself, but thought to check first to see if anyone has already done this and is willing to share.

Thanks in advance for any help.

[UPDATE  06/28/2016]

As there appears to not be a readily available solution I created a class to provide Oauth 1.0 authentication.  This class is attached in a zip file.  Methods are provided that generate a signature for a given URL request based on a consumer key and consumer secret.

This is a bit of an IRIS question but also and OAuth 2.0 questions:

I am using %OAuth2.JWT.JWTToObject() to "validate" a JWT.  My questions:

- While I am checking claims with the returned body, does the return status of the method "count" as a validation step? In other words, if I weren't checking claims and $$$OK was returned from that method call (passing in the token and public keys), I could feel confident that this token came from the expected auth server?
