Dropbox Sign requirements

SAML SSO requires a Dropbox Sign Premium plan.

authentik configuration​

To support the integration of Dropbox Sign with authentik, you need to create property mappings and an application/provider pair in authentik.

Create property mappings​

Dropbox Sign expects the SAML assertion to include FirstName and LastName attributes. Because authentik stores a user's full name as a single string, create SAML provider property mappings that split the full name into first and last names.

  1. Log in to authentik as an administrator and open the authentik Admin interface.

  2. Navigate to Customization > Property Mappings and click Create.

  3. Select SAML Provider Property Mapping as the property mapping type and click Next.

  4. Create a property mapping with the following values:

    • Name: Dropbox Sign FirstName

    • SAML Attribute Name: FirstName

    • Expression:

      name = request.user.name or request.user.username
      return name.split(" ", 1)[0]

  5. Click Finish to save the property mapping.

  6. Repeat steps 2-5 to create the following additional SAML provider property mapping:

    • Name: Dropbox Sign LastName

    • SAML Attribute Name: LastName

    • Expression:

      name = request.user.name or request.user.username
      return name.rsplit(" ", 1)[-1] if " " in name else ""

Create an application and provider in authentik​

SAML provider changes in authentik 2026.5

authentik 2026.5 introduces changes to how the SAML provider behaves. Specifically, the provider now automatically sets the Issuer value to: https://authentik.company/application/saml/<application_slug>/metadata/

Older versions of authentik set this value to authentik by default. If you're running an older version, please set Issuer to https://authentik.company/application/saml/<application_slug>/metadata/, where <application_slug> is the slug that you selected for the application.

  1. Log in to authentik as an administrator and open the authentik Admin interface.
  2. Navigate to Applications > Applications and click New Application to open the application wizard.
    • Application: provide a descriptive name, an optional group for the type of application, the policy engine mode, and optional UI settings. Take note of the slug value because it will be required later.
    • Choose a Provider type: select SAML Provider as the provider type.
    • Configure the Provider: provide a name (or accept the auto-provided name), the authorization flow to use for this provider, and the following required configurations.
      • Set ACS URL to https://app.hellosign.com/account/ssoLogIn.
      • Set Audience to https://app.hellosign.com.
      • Under Advanced protocol settings:
        • Set Signing Certificate to any available certificate.
        • Set NameID Property Mapping to authentik default SAML Mapping: Email.
        • Set Default NameID Policy to Email address.
        • Add the Dropbox Sign FirstName and Dropbox Sign LastName property mappings that you created in the previous section.
    • Configure Bindings (optional): you can create a binding (policy, group, or user) to manage the listing and access to applications on a user's Application Dashboard page.
  3. Click Submit to save the new application and provider.

Download and prepare the signing certificate​

  1. Log in to authentik as an administrator and open the authentik Admin interface.
  2. Navigate to Applications > Providers and click the name of the newly created Dropbox Sign provider.
  3. Under Related objects > Download signing certificate, click Download.
  4. Open the downloaded certificate file in plain text, remove the first and last lines (-----BEGIN CERTIFICATE----- and -----END CERTIFICATE-----), then remove all line breaks from the remaining certificate text. This certificate text will be required in the next section.

Dropbox Sign configuration​

  1. Log in to Dropbox Sign as an administrator.
  2. Hover over your email address in the top-right corner, then select Admin console.
  3. In the left sidebar, click Security, then locate SSO.
  4. Configure the following required settings:
    • Identity Provider Single Sign-On URL: https://authentik.company/application/saml/<application_slug>/
    • Identity Provider Issuer: https://authentik.company/application/saml/<application_slug>/metadata/
    • X.509 Certificate: paste the certificate text that you prepared from the authentik signing certificate.
  5. Keep Allow standard logins for admins enabled while testing the SAML configuration.
  6. Click Save.

Configuration verification​

To confirm that authentik is properly configured with Dropbox Sign, open the Dropbox Sign application from the authentik Application Dashboard. You should be redirected to Dropbox Sign and signed in as the matching Dropbox Sign user.

After you verify that SAML SSO works, decide whether to disable Allow standard logins for admins in Dropbox Sign.
