Re: 4D Web Application and SAML or OpenID Connect
Hi Thanks for all the responses. As always, there is more than one way to do it. Looks like OpenID Connect may be simpler. We've already got some OAuth code in use for external application interfaces.

Hi Keith, Yes, I have experience with Open ID Connect. A customer of mine got the requirement to handle user authentication through an OpenID Connect provider. I think the customer was using Microsoft’s Azure Active Directory. So basically I had to replace the login screen of their desktop application with the login screen of the OpenID provider. If you are familiar with OAuth2, then it works quite the same. In a web area we show the provider’s login screen. Upon successful login, the 4D app receives a JSON Web Token (JWT), that contains the user’s information with a digital signature on it. This JWT then needed to be verified against X509 digital certificates in the JWKS format. That was a bit more of a technical challenge, but I developed this functionality for NTK Plugin. I do not remember the exact details because it is almost 2 years ago that I have developed this. But let me know if you have any questions or need help.

AW: 4D Web Application and SAML or OpenID Connect
Hi, we do something in this area. We use an Apache webserver in front of the 4D web server as a reverse proxy or gateway. There is an Apache module called mod_auth_openidc (https://github.com/zmartzone/mod_auth_openidc) which is configured to use an external identity provider (IP). In our case this is a Keycloak server (https://www.keycloak.org/). On the 4D side you have to check the additional headers delivered by the module only. Further questions regarding the configuration of the module I'm not able to answer, this were done by external colleagues. There is comprehensive documentation on the mentioned websites.

Re: 4D Web Application and SAML or OpenID Connect
Keith, Hi. It looks like it would be a lot of work to do a native implementation of OIDC in 4D? Why not instead look at providing support for services such as OneLogin, Auth0, AWS Cognito instead? Certainly the former 2 of those appear to offer REST APIs to. Cognito doesn't offer a REST API but there is a PHP library (I did an integration with that last year, non-4D solution) but for your purposes you can avoid PHP I think by integrating with the aws-cli and LEP?

Re: Losing memory on 4D web application
Aparajita: We loved ObjectTools at Jonoke for well over a decade. We could not have done what we did without it. It was fantastic. Thanks for ObjectTools over all those years. We never had a memory leak from it while we used it. It is great having plug-in developers creating tools for us, while 4D concentrates its development efforts on other things. As developers we win. Yes, we now use 4D Objects. Adam wrote our own dot notation tool. Yes, we will likely discard that to the use of 4D’s in the next year, but again it is getting the job done, while 4D was getting other things done in 4D.

Losing memory on 4D web application
I have a large 4D web intranet application that, over the course of a week, runs out of memory. It is running 4D Server 16R4 on Windows Server 2012, with 16GB RAM, and no other applications are running on it. This application does a lot of calls to a middleware server that returns large quantities of data in XML format. The returned data is parsed using the XML DOM commands, but in each case I am calling the DOM CLOSE XML command. I have checked that all blobs are being resized to 0, and I have included at the bottom of each web page a wrapper that clears variables and reduces all table selections to 0. jQuery ajax calls are used extensively in the web pages. The resulting data from these ajax calls is passed back from 4D in html files that use 4D tags and formats the data into JSON format. At the bottom of each of these files I have also put the Clear Variables and Reduce Selection wrappers. What am I missing? Are there any tools or logs that will tell which methods are not releasing memory? What else should I be checking?
