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:

1. In Proxmox, navigate to Datacenter > Realms > Add OpenID Connect Server

2. 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

3. 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 the tsidp server (default: "idp", Docker only)
• TS_STATE_DIR: State directory (default: "/var/lib/tsidp", Docker only)
