Just-in-Time Provisioning
An identity management approach that creates user accounts automatically at the moment of first successful authentication, eliminating manual setup.
What is Just-in-Time Provisioning?
Just-in-Time (JIT) Provisioning is an identity management approach where user accounts are automatically created in a Service Provider (SP) system at the moment of first successful authentication, rather than being pre-provisioned.
How JIT works:
- User authenticates via federated SSO (SAML/OIDC) for the first time
- The SP receives the authentication assertion containing user attributes
- Since no account exists, the SP automatically creates one using the assertion data
- User is logged into their newly created account
Benefits:
- No manual provisioning: Eliminates IT tickets for account creation
- Reduced overhead: No pre-provisioning of accounts that may never be used
- Always current: User attributes are populated from the authoritative IdP
- Simplified onboarding: New users can access applications immediately
Analogy
Think of just-in-time provisioning like a hotel that creates your room key when you check in at the front desk, rather than having your key ready days in advance. The room is prepared (user account) exactly when you need it, not before. This means no wasted keys for no-shows and no manual key preparation.
Types and Use Cases
- Enterprise SSO: New employees get instant access to SaaS apps (Salesforce, Slack) via their corporate IdP without IT intervention
- B2B Portals: Partner users automatically get accounts when they first log in via their corporate IdP
- Customer SSO: Customers who sign in with Google/Facebook get accounts created automatically
- Migration Scenarios: During identity system migration, JIT provisions users as they first log into the new system
How it Works
Just-in-Time Provisioning vs Pre-Provisioning (SCIM)
Just-in-Time Provisioning
Pre-Provisioning (SCIM)
JIT Provisioning creates accounts on first login
Pre-Provisioning (SCIM) creates accounts in advance via API sync ; JIT is event-driven (user triggers it); SCIM is scheduled or change-driven (HR event triggers it) ; JIT requires no integration setup; SCIM requires API integration and attribute mapping
JIT may cause slight delay on first login (account creation)
SCIM accounts are ready immediately ; JIT doesn't handle deprovisioning well; SCIM includes deprovisioning : Both can work together - JIT for creation, SCIM for ongoing sync
Best Practices for Just-in-Time Provisioning
- Use JIT + SCIM together: JIT for initial account creation, SCIM for ongoing attribute sync and deprovisioning
- Define attribute mapping: Configure how IdP attributes map to SP user profile fields
- Set default roles: Define default permissions for JIT-provisioned users
- Implement domain restrictions: Only JIT-provision users from authorized email domains
- Log JIT events: Track all JIT provisioning events for audit and troubleshooting
How LoginRadius Powers Just-in-Time Provisioning
LoginRadius supports JIT provisioning for federated authentication. When users authenticate via SAML/OIDC from enterprise IdPs (Okta, Azure AD) or social login (Google, Facebook), LoginRadius auto-creates user profiles with attributes extracted from the authentication assertion. This eliminates manual account setup for new users.
FAQs
Yes, JIT provisioning is secure when properly configured. The SP validates the IdP's signature on the assertion, so only authenticated users from trusted IdPs can trigger account creation. However, ensure: (1) Validate assertions - verify signatures and timestamps, (2) Restrict domains - only allow JIT from authorized email domains, (3) Set appropriate roles - JIT-created accounts should start with minimal privileges.
JIT creates accounts when users first log in - it's reactive and event-driven. SCIM creates accounts proactively through API calls - it's automated and schedule/event-driven. JIT doesn't handle deprovisioning (account removal on user departure), while SCIM does. Best practice is to use both: JIT for initial account creation, SCIM for ongoing updates and deprovisioning.
LoginRadius supports JIT provisioning for federated SSO scenarios. When a user authenticates via SAML or OIDC from an external IdP, LoginRadius can automatically create a user profile if one doesn't exist. This works for both enterprise federation (Okta, Azure AD) and social login (Google, Facebook). LoginRadius extracts attributes from the assertion and maps them to user profile fields.
