+# Synology Setup with tsidp
+
+This section covers:
+- Configuring Synology to use an existing tsidp instance for authentication
+
+## Configure Synology to Use tsidp
+
+This example assumes:
+- Synology NAS: `https://nas.yourtailnet.ts.net:5001`
+- tsidp instance: `https://idp.yourtailnet.ts.net`
+
+### Setup Tailscale on Synology
+
+1. **Install and configure Tailscale** on your Synology NAS
+   - Follow the [official Tailscale guide for Synology](https://tailscale.com/kb/1131/synology)
+   - Ensure you've completed the hostname configuration steps mentioned in that guide
+
+### Register Synology as a Client in tsidp
+
+1. **Visit** `https://idp.yourtailnet.ts.net` and click "Add New Client"
+
+   ![Add New Client](add-oidc-client.png)
+
+2. **Configure the client**:
+   - **Redirect URI**: Synology only appears to support a single redirect URI.
+     - `https://nas.yourtailnet.ts.net:5001`
+   - Save the generated Client ID and Client Secret
+
+### Configure OpenID Connect in Synology
+
+1. **Navigate to** Control Panel → Domain/LDAP → SSO Client (Tab)
+
+2. **Enable OpenID Connect**:
+   - Check the "Enable OpenID Connect SSO service" checkbox
+   - Click the "OpenID Connect SSO Settings" button
+
+   ![Enable OpenID Connect](enable-openid-connect.png)
+
+3. **Configure the OpenID Connect settings**:
+   - **Profile**: OIDC
+   - **Account type**: Domain/LDAP/local
+   - **Name**: `tsidp`
+   - **Well known URL**: `https://idp.yourtailnet.ts.net/.well-known/openid-configuration`
+   - **Application ID**: (from tsidp)
+   - **Application secret**: (from tsidp)
+   - **Redirect URI**: (the one configured in tsidp)
+   - **Authorization scope**: `openid profile email`
+   - **Username claim**: `username`
+
+   ![Configure OpenID Connect Settings](configure-openid-settings.png)
+
+4. **Important**: Create Synology user accounts
+   - Synology must have a local user account matching your Tailscale username
+   - If your Tailscale username is `example@github`, create a Synology user named `example`
+   - The OpenID Connect integration will authenticate users but requires matching local accounts
+
+### Test Authentication
+
+1. **Open an incognito browser window** and navigate to `https://nas.yourtailnet.ts.net:5001`
+
+2. **Log in** using Tailscale authentication
+   - You should be prompted to authenticate via tsidp
+   - After successful authentication, you should be logged into Synology
+
+3. **Close the incognito window**
+
+## Final Verification
+
+Log out of Synology and log back in using Tailscale authentication to verify everything is working correctly.
