[Bug] In-memory node "user" not updated after headscale user rename and OIDC change

Is this a support request?

Current Behavior

If I:

1. Change an OIDC user's email "username" from say [email protected] to [email protected]
2. Rename the user in Headscale via headscale user rename -i <id> --new-name [email protected]
3. Log the user back into Headscale

Then headscale user list shows their updated Username and Email (from the OIDC login). Also headscale node list --user [email protected] pulls back their owned nodes.

However headscale node list shows their old email ([email protected]) for the node's "User". I'm assuming the in-memory map just isn't updated, as restarting Headscale results in the new/correct user ([email protected]).

Expected Behavior

I'd expect headscale node list have updated User information after changes without requiring a restart.

Steps To Reproduce

See initial section for steps.

Environment

- OS: Ubuntu 24
- Headscale version: v0.29.3
- Tailscale version: N/A

Runtime environment

• Headscale is behind a (reverse) proxy
• Headscale runs in a container
