Synology DSM

Tested Versions

Before You Begin

Common Notes

  1. You are required to utilize a unique client id for every client.
  2. The client id on this page is merely an example and you can theoretically use any alphanumeric string.
  3. You should not use the client secret in this example, We strongly recommend reading the Generating Client Secrets guide instead.

Specific Notes

Important Note: Synology DSM does not support automatically creating users via OpenID Connect 1.0. It is therefore recommended that you ensure Authelia and Synology DSM share a LDAP server.


This example makes the following assumptions:

  • Application Root URL:
  • Authelia Root URL:
  • Client ID: synology-dsm
  • Client Secret: synology-dsm_client_secret



To configure Synology DSM to utilize Authelia as an OpenID Connect 1.0 Provider:

  1. Go to DSM.
  2. Go to Control Panel.
  3. Go To Domain/LDAP.
  4. Go to SSO Client.
  5. Check the Enable OpenID Connect SSO service checkbox in the OpenID Connect SSO Service section.
  6. Configure the following values:
    • Profile: OIDC
    • Name: Authelia
    • Well Known URL:
    • Application ID: synology-dsm
    • Application Key: synology-dsm_client_secret
    • Redirect URL:
    • Authorisation Scope: openid profile groups email
    • Username Claim: preferred_username
  7. Save the settings.


The following YAML configuration is an example Authelia client configuration for use with Synology DSM which will operate with the above example:

- id: synology-dsm
  description: Synology DSM
  secret: '$plaintext$synology-dsm_client_secret'
  public: false
  authorization_policy: two_factor
    - openid
    - profile
    - groups
    - email
  userinfo_signing_algorithm: none
