Error connecting Windows users via SSO

[artkrp31]

There is a problem with connecting Windows users. Previously, the user could connect to NetBird, which is hosted on its own infrastructure. A few days later, this user tries to connect again and receives the error rpc error: code = PermissionDenied desc = invalid user

Steps to reproduce the behavior:

1. Go to NetBird client
2. Click on connect
3. See error

Successful connection to NetBird

self-host NetBird's control plane.

0.45.1

Is any other VPN software installed?

No

@lixmal, Hello.
Yes, I've read it. It states that this error occurs if multiple users try to connect to NetBird from the same device, but the problem is that the user is alone. The connection is made via SSO Keycloak. This problem definitely does not arise due to the fact that users are different, there is always 1 user connected behind 1 device. The problem occurs unexpectedly.

I encountered a similar issue. Keycloak as SSO, operating system was Fedora 42.
