Users / Roles not showing up in Instances

OS Name/Version: Debian “Trixie” 13.5.0

Product Name/Version: v2.7.2.6, built 14/05/2026 19:04

Problem Description:

Hi everyone,

I recently installed AMP Professional and successfully set up my first server.

I was also able to create a second user in ADS, and this user can perform all tasks without any issues using the Super Admin role.

Now, however, I wanted to create a third user who only has access to certain instances. I was able to successfully create the user in ADS and can log in with that account. Additionally, they can see both instances (permission: Manage).

But when I try to manage the permissions for this user within the instance, I hit a wall. I can neither create new users nor view existing ones in the instances.

Deployment Logs gives these informations:

```vbnet

Steps to reproduce:

  • Login with Admin on ADS
  • Create User in Usermanagement (ADS)
  • Assign Instance Managment Permission
  • Manage Instance
  • Try to add Permissions to new created User

or

  • Manage Instance
  • Try to add User → Nothing happens
