Recently, we had a project which required us to connect to a MySQL server from .NET Core with a client certificate authentication. While this seemed fairly trivial, we have hit some issues after deploying the application to Azure App Service.
I have been running this blog and bunch of other projects on a local shared hosting called WEDOS for something over 3 years. They offer some great services for real good price, however after couple of issues and temptation I decided to move away to an Azure VM. We are going to take a look at how I did the move and what technologies I am using the background.
When authenticating a user, you might want to persist the state through the authentication request – for example whether the user is authenticating for some special action like organizational signup or simply some state of your application. ASP.NET Core makes this very easy.Continue reading “Passing state through authentication in ASP.NET Core”
I previously wrote about the possibility of remote debugging PHP apps in Microsoft Azure using ngrok. This solution wasn’t much secure and required the use of 3rd party software. During build, Microsoft announced support for SSH directly into the App Service on Linux instance and thanks to that, we no longer need ngrok or similar software and can do with just Azure CLI and VS Code. In this article, we are going to look at the setup.Continue reading “Remotely debugging PHP on App Service on Linux”
I haven’t touch Node.js much lately, however, back while I have been working with it, I was always curious, how to leverage both Passport.js with Azure AD and using ADAL for Node.js together in order to have ADAL handle the tokens, refreshes, cache etc. In the end, I have come up with a solution which I am going to share below.Continue reading “Using ADAL for Node.js with Passport.js”
We have been migrating couple of projects to ASP.NET Core 2.0 recently. Amongst the major changes in ASP.NET Core 2.0, probably the biggest change has been done in the Authentication. I have written an article about cookie size in ASP.NET Core which explains the basic issue with too many claims in the identity. ASP.NET Core 2.0 OIDC addresses this by removing some of the token values from the identity on the background.Continue reading “Missing claims in ASP.NET Core 2.0 OpenID Connect”
Based on my previous post about B2B guest access to application, I made another sample called MyGroups. I think it demonstrates practical usage of both B2B guest access, Office 365 Groups and Microsoft Graph.
MyGroups can be used to display all Office 365 Groups to which the user has been added and additionally list direct links to the group’s SharePoint site, which is something we have been in need of internally within our company.
In the HomeController, you can find the call which is being made to Microsoft Graph’s groups endpoint to get the group’s site information – it is being made in parallel to make the request shorter for the user – generally, on average, it took about 1 second to get the site details of each group.
If you would like to use the code, just go ahead and grab the source from GitHub!
Since Microsoft’s Azure AD got the Business-to-Business (B2B) functionality, it has enabled a broad variety of new scenarios to be developed. It for example makes sharing various resources and information within applications much more easier. Today we are going to investigate the way to build an application which is not only a multi-tenant one, but also supports the user to be member of multiple directories.Continue reading “Creating a multi-tenant application which supports B2B users”
When you attempt to deploy an ASP.NET Core project to App Service on Linux, you may run into an error during the build process – Object reference not set to an instance of an object. When you try to deploy the project to App Service on Windows, everything works, so where is the issue?Continue reading “Deploying ASP.NET Core to App Service on Linux”
