The error AADSTS500113 indicates that there is no reply address registered for the application you are trying to authenticate with. In the context of Azure Bastion and Entra ID, the application you are looking for is likely related to the Bastion service that allows you to connect to your VMs using the native client.
The Azure Bastion Native Client is not a standalone application that you install; rather, it is part of the Azure Bastion service that facilitates connections to VMs using RDP or SSH. When you use the Azure Portal to connect to a VM, the Bastion service manages the authentication process, including redirect URIs.
If you do not see an application named "Azure Bastion Native Client" in your App Registrations, it may be due to the specific configuration of your Azure environment or the way the Bastion service is set up. You should ensure that your Azure Bastion configuration is correct and that the necessary permissions and redirect URIs are properly set up in the Azure portal.
To resolve this issue, you may want to check the following:
- Ensure that the Azure Bastion service is correctly configured in your Azure environment.
- Verify that the redirect URIs for the Bastion service are correctly registered in the App Registrations section of Azure Active Directory.
- If necessary, consult the Azure documentation or support for further assistance regarding the Bastion service and its integration with Entra ID.
