SSO configuration with AD FS

danger

Before configuring SSO, make sure that the APP_URL parameter in config.env matches the current Passwork domain, example — APP_URL=https://passwork.example.com

The following server names are used as examples:

• Provider (IDP) — ad-fs.passwork.local
• Passwork server (SP) — passwork.example.com

Adding a Relying Party Trust

Perform the steps in the — Add Relying Party Trust Wizard:

1. Claims aware;
2. Enter data about the relying party manually;
3. Fill in the Display name (example: passwork-sp);
4. Skip the step — Configure Certificate, click Next;
5. At the Configure URL step:
   1. Enable support for the SAML 2.0 WebSSO protocol;
   2. Copy from Passwork in — Settings and Users → SSO Settings — the Reply URL;
   3. Paste into Relying party SAML 2.0 SSO service URL — https://passwork.example.com/api/v1/sso/acs
6. At the Configure Identifiers step:
   1. Copy from Passwork in — Settings and Users → SSO Settings — the Identifier;
   2. Paste into Relying party trust identifier — https://passwork.example.com/api/v1/sso/metadata
7. Skip the step — Choose Access Control Policy, click Next;
8. Skip the step — Ready to Add Trust, click Next;
