I need enterprise SSO with SAML and OIDC

I can help with that. If you need enterprise SSO, the two common standards are:
- SAML 2.0 — very common for older enterprise IdPs and SaaS apps
- OIDC (OpenID Connect) — modern, API-friendly, built on OAuth 2.0
Quick recommendation
If you’re building a new product, support both if possible:
- OIDC first for better developer experience and mobile/API support
- SAML for enterprise procurement and compatibility with legacy IdPs like older ADFS or certain enterprise setups
What you typically need to implement
For SAML
- Service Provider (SP) support
- Metadata import/export
- ACS URL handling
- Entity ID
- Certificate-based signing / optional encryption
- Assertion validation
- Attribute mapping (email, name, groups, etc.)
- IdP-initiated and SP-initiated login support
For OIDC
- Authorization Code flow
- PKCE support
- Discovery endpoint (
/.well-known/openid-configuration) - JWKS key validation
- ID token verification
- Refresh tokens if needed
- Claims mapping and group/role handling
Enterprise features often expected
- Just-in-time provisioning
- SCIM for user lifecycle management
- Group/role sync
- SSO domain restrictions
- Audit logs
- MFA enforcement via IdP
- Multiple IdP connections per tenant
- Test connection and metadata validation
- Role-based access control mapping
Common IdPs you may need to support
- Okta
- Microsoft Entra ID (Azure AD)
- Google Workspace
- Ping Identity
- OneLogin
- Auth0
- ADFS
Implementation options
- Build in-house
- Use an identity broker like:
- Auth0
- Okta
- WorkOS
- Clerk
- FusionAuth
- Keycloak
If you want, I can help you with any of these next steps:
- Design an SSO architecture for your app
- Compare SAML vs OIDC for your use case
- Give implementation examples
- Recommend a vendor/platform
- Draft enterprise SSO requirements for your engineering team
If you tell me your stack and whether you want to build vs buy, I can suggest the best approach.
