Give nodeBackend a RouteManager and keep it in sync as routing inputs change: full netmaps resync the whole peer set (removals plus no-op-cheap upserts), incremental netmap deltas mirror their peer upserts and removes into the same mutation batch, and authReconfigLocked pushes the routing-relevant prefs (exit node, subnet route acceptance, OneCGNAT) after resolving the exit node's stable ID to its current numeric node ID. A selected exit node that doesn't resolve to a current peer (a nonexistent node, or MDM's "auto:any" placeholder awaiting resolution) is not the same as no exit node: per the long-standing ipn.Prefs.ExitNodeID contract, it blackholes internet traffic rather than letting it escape to the local network. RouteManager's Prefs gains an ExitNodeSelected bit so its OS route set keeps the default routes in that case, with no outbound peer to carry them, matching what routerConfigLocked does today, as pinned by TestRouterConfigExitNodeBlackhole in the previous commit. All mutations happen with nodeBackend.mu held, satisfying the RouteManager's serialized Begin/Commit contract. Nothing consumes its snapshots yet; the wgengine data plane and OS router wiring come next.

tsidp - Tailscale OpenID Connect (OIDC) Identity Provider
tsidp is an OIDC Identity Provider (IdP) server that integrates with your Tailscale network. It allows you to use Tailscale identities for authentication in applications that support OpenID Connect, enabling single sign-on (SSO) capabilities within your tailnet.
Prerequisites
- A Tailscale network (tailnet) with magicDNS and HTTPS enabled
- A Tailscale authentication key from your tailnet
- Docker installed on your system
Installation using Docker
Pre-built image
A pre-built tsidp image exists at tailscale/tsidp:unstable.
Building from Source
# Clone the Tailscale repository
git clone https://github.com/tailscale/tailscale.git
cd tailscale
# Build and publish to your own registry
make publishdevtsidp REPO=ghcr.io/yourusername/tsidp TAGS=v0.0.1 PUSH=true
Running the Container
Replace YOUR_TAILSCALE_AUTHKEY with your Tailscale authentication key:
docker run -d \
--name tsidp \
-p 443:443 \
-e TS_AUTHKEY=YOUR_TAILSCALE_AUTHKEY \
-e TAILSCALE_USE_WIP_CODE=1 \
-v tsidp-data:/var/lib/tsidp \
ghcr.io/yourusername/tsidp:v0.0.1 \
tsidp --hostname=idp --dir=/var/lib/tsidp
Verify Installation
docker logs tsidp
Visit https://idp.tailnet.ts.net to confirm the service is running.
Usage Example: Proxmox Integration
Here's how to configure Proxmox to use tsidp for authentication:
-
In Proxmox, navigate to Datacenter > Realms > Add OpenID Connect Server
-
Configure the following settings:
- Issuer URL:
https://idp.velociraptor.ts.net - Realm:
tailscale(or your preferred name) - Client ID:
unused - Client Key:
unused - Default:
true - Autocreate users:
true - Username claim:
email
- Issuer URL:
-
Set up user permissions:
- Go to Datacenter > Permissions > Groups
- Create a new group (e.g., "tsadmins")
- Click Permissions in the sidebar
- Add Group Permission
- Set Path to
/for full admin access or scope as needed - Set the group and role
- Add Tailscale-authenticated users to the group
Configuration Options
The tsidp server supports several command-line flags:
--verbose: Enable verbose logging--port: Port to listen on (default: 443)--local-port: Allow requests from localhost--use-local-tailscaled: Use local tailscaled instead of tsnet--hostname: tsnet hostname--dir: tsnet state directory
Environment Variables
TS_AUTHKEY: Your Tailscale authentication key (required)TS_HOSTNAME: Hostname for thetsidpserver (default: "idp", Docker only)TS_STATE_DIR: State directory (default: "/var/lib/tsidp", Docker only)TAILSCALE_USE_WIP_CODE: Enable work-in-progress code (default: "1")
