Tailscaled had no way to seed device-scope syspolicy settings short of environment variables or a custom store wired up out of tree. Add a --syspolicy-file flag whose default points at a well-known JSON file that, when present, is parsed as a map[string]any and registered as a device-scope policy source. The default path is /etc/tailscale/syspolicy.json on every non-Windows platform (Linux, the BSDs, illumos/Solaris, and tailscaled-without-the-GUI on macOS) and %ProgramData%\Tailscale\syspolicy.json on Windows. The flag lets users running tailscaled by hand (development, custom installs) point it at an alternate file, and "" disables the load entirely. JSON values map to setting types as expected: strings to StringValue/PreferenceOptionValue/VisibilityValue/DurationValue (e.g. "24h" parsed by time.ParseDuration), booleans to BooleanValue, numbers to IntegerValue, and string arrays to StringListValue. The file is validated against the registered setting definitions at load time so unknown keys and value/type mismatches fail startup loudly rather than producing surprising defaults at first read. When HuJSON support is linked into the build (default; opt out with ts_omit_hujsonconf), the file may use HuJSON (comments, trailing commas). With ts_omit_hujsonconf it must be pure standard JSON. This mirrors the pattern used by ipn/conffile. On Windows the JSON file and the existing HKLM registry store both register at DeviceScope. rsop merges later-registered same-scope sources over earlier ones, so per-key values in the file override the registry while keys absent from the file fall back to the registry. The loader is registered via a feature.Hook from a file gated by !ts_omit_syspolicy, and called from main after flag parsing. tsnet still does not depend on the root syspolicy package, so embedders don't pick this up implicitly.

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")
