What should I use for multi-tenant SSO with role mapping?

For multi-tenant SSO with role mapping, the best choice is usually an identity provider (IdP) or CIAM platform that supports SAML/OIDC plus tenant-aware claims/groups.
Good options
- Auth0 / Okta Customer Identity
- Good for B2B SaaS, org/tenant support, SSO, RBAC, and custom claims
- Microsoft Entra ID (Azure AD)
- Best if many customers already use Microsoft for SSO
- Strong SAML/OIDC support and enterprise app integrations
- AWS Cognito
- Works, but role mapping and enterprise SSO are more limited/awkward than dedicated IdPs
- Keycloak
- Strong open-source option if you want full control and can operate it yourself
- Ping Identity / OneLogin
- Strong enterprise SSO and federation support
- WorkOS
- Very good if you want to add enterprise SSO quickly in a SaaS app
- Especially useful for multi-tenant B2B and SCIM directory sync
What matters for role mapping
Look for support for:
- Organizations / tenants
- SAML and/or OIDC
- Custom claims / attributes
- Group sync / SCIM
- Per-tenant role assignment
- JIT provisioning and directory sync
Practical recommendation
If you’re building a B2B SaaS:
- WorkOS if you want fastest enterprise SSO integration
- Auth0/Okta if you want a broader full-featured identity platform
- Keycloak if you want open-source/self-hosted
Common pattern
- Tenant logs in via their IdP
- IdP sends assertions/claims with user email, groups, or roles
- Your app maps those claims to internal roles like:
tenant_adminbilling_adminmemberviewer
- Store the mapping per tenant, not globally
If you want, I can also suggest the best option based on your stack (AWS/Azure/GCP, self-hosted vs SaaS, SAML vs OIDC, expected number of tenants).
