Your security team just discovered 847 dormant user accounts across your systems. Each one represents a potential breach waiting to happen.
While you scramble to audit and deactivate these ghost accounts, just-in-time provisioning eliminates this nightmare entirely by creating user accounts only when authentication actually occurs.
What is Just-in-Time (JIT) Provisioning?
Just-in-Time (JIT) provisioning is a method that automatically creates user accounts for applications at the exact moment a user first logs in.
Instead of setting up accounts for every potential user in advance, JIT provisioning uses details from an identity provider (like Okta or Azure AD) and creates the account only when authentication succeeds, usually through SSO protocols such as SAML or OpenID Connect.
When a user tries to access an application, the identity provider sends key details (like name, email, department, and roles) to the service. The application reads this information and instantly creates the user’s profile, with no manual steps needed from IT.
JIT provisioning is especially useful for organizations with temporary or changing user bases, such as universities with rotating students, companies hiring contractors, or SaaS platforms serving different clients.
How Does Just-in-Time (JIT) Provisioning Work?
JIT user provisioning follows a precise six-step workflow that transforms authentication events into instant account creation.
Step 1: Authentication Request Initiation A user attempts to access an application through Single Sign-On. The application immediately redirects them to the configured Identity Provider for credential verification.
Step 2: Identity Provider Verification The IdP validates user credentials through various methods:
- Username and password combinations
- Multi-factor authentication tokens
- Biometric verification systems
- Certificate-based authentication protocols
Step 3: Assertion and Token Exchange Upon successful verification, the IdP generates a SAML assertion or OIDC token containing critical identity attributes. This payload includes username, email address, group memberships, role assignments, and custom metadata fields.
Step 4: Real-Time Profile Creation The Service Provider receives the assertion and immediately checks for existing user records. If none exist, just-in-time user provisioning creates a complete profile using the provided attributes. Existing users receive updated information reflecting any role or department changes.
Step 5: Dynamic Role Assignment Advanced implementations include attribute-based role mapping. Users from "Finance" groups receive different permissions than "Engineering" members, ensuring appropriate access levels from the first login attempt.
Step 6: Comprehensive Audit Logging Security-conscious organizations enable detailed event logging and audit trails, capturing every provisioning action for compliance monitoring and forensic analysis.
This automated mechanism eliminates manual user lifecycle management, particularly valuable for high-turnover organizations experiencing rapid growth.
Benefits of Just-in-Time (JIT) Provisioning
Just-in-Time provisioning makes life easier by simplifying access, improving security, cutting costs, and reducing the IT team’s workload.
1. Operational Efficiency Revolution: SAML JIT provisioning eliminates pre-provisioning requirements, creating seamless onboarding experiences. Enterprise environments managing employees, contractors, partners, and clients benefit from instant access without IT intervention.
In a consulting firm using Okta, as soon as a new contractor logs in for the first time, their account is created and they receive immediate access to the systems they need. There is no waiting period, no back and forth with IT, and no manual steps involved. Everything happens automatically, which saves time and effort for both the contractor and the company.
2. Enhanced Security Posture: Zero dormant accounts mean zero attack surfaces from unused credentials. Just-in-time provisioning SSO ensures only authenticated users receive access, dramatically reducing exploitation opportunities.
If a user is turned off or removed in the Identity Provider, they won’t be able to log in again. Because of this, the system won’t create their account again by mistake. This helps avoid keeping old or unused user accounts in the system.
3. Real-Time Attribute Synchronization: User roles, departments, and permissions stay current with Identity Provider data. This ensures accurate role-based access control implementation and maintains alignment with organizational policies and structural changes.
4. Infinite Scalability Potential: Cloud-native just-in-time user provisioning scales efficiently with growing user bases. Organizations handle thousands of concurrent users without proportional administrative workload increases, supporting explosive growth scenarios.
5. Significant Cost Optimization: Since provisioning occurs only for active users:
- SaaS application license costs decrease substantially
- IT support overhead drops dramatically
- User management time requirements plummet
6. Superior User Experience: From their very first login, users get instant access to the applications they need. They do not have to wait for IT to manually create accounts or approve access requests.
What is the Difference Between SAML and JIT?
The table below highlights the key differences between SAML and JIT provisioning based on purpose, function, timing, and setup.
Quick Breakdown of Each Difference:
- Purpose: SAML helps users log in. JIT creates the user account when login happens.
- Main Function: SAML just passes user details. JIT reads those details and uses them to create an account.
- When It Happens: SAML runs during the login process. JIT kicks in after the login is successful.
- Setup Requirement: SAML setup is needed on both the Identity Provider (like Okta) and the Service Provider (like Salesforce). JIT setup mostly happens on the Service Provider side.
- Example: With SAML, the user logs in to Salesforce through Okta. With JIT, the Salesforce user account is created automatically the first time the person logs in.
How Do You Implement Just-in-Time Provisioning?
Implementing SAML JIT provisioning requires careful integration between Service Providers and Identity Providers. Here's the comprehensive implementation process:
Step 1: Configure Identity Provider Prerequisites Ensure your IdP supports SAML 2.0 or OpenID Connect protocols for proper attribute mapping. Enable essential user profile attributes:
- First and last name fields
- Primary email addresses
- Group membership data
- Role assignment information
Step 2: Enable JIT in Service Provider
- Access the Admin Console interface
- Navigate to Directory > Directory Integrations
- Select your AD/LDAP Integration
- Under Provisioning tab, click "To Okta"
- Enable "Create and update users on login"
- Save configuration changes
Step 3: Configure Precise Attribute Mapping Map SAML assertion or OIDC token attributes to user profile fields:
- Username mapping requirements
- Department assignment logic
- User type classifications (internal vs external)
- Custom attribute handling
Exact mapping prevents provisioning failures and incomplete profile creation.
Step 4: Comprehensive Testing Protocol Test with accounts non-existent in the application. Successful JIT user provisioning should:
- Create complete user profiles automatically
- Grant immediate access post-authentication
- Log all provisioning activities properly
Step 5: Enable Audit and Compliance Logging Configure detailed logging for provisioning events. Compliance-heavy industries like finance and healthcare require traceable just-in-time provisioning actions for regulatory adherence.
Challenges in Just-in-Time (JIT) Provisioning
While JIT provisioning offers many benefits, it also comes with technical and operational challenges that organizations must plan for carefully.
1. Identity Provider Dependency Risks If Okta or Azure AD experiences downtime, user provisioning and authentication fail completely. No fallback account creation methods exist without manual configuration backup systems.
2. Attribute Mapping Complexity Issues Mismatched user attributes during token exchange create:
- Partial account creation scenarios
- Complete provisioning failure events
- Inconsistent user access level assignments
3. Limited Pre-Approval Workflow Support Unlike SCIM systems, JIT provisioning lacks complex approval workflows or role-based provisioning gates before account activation occurs.
4. Potential Audit Trail Gaps Improper configuration creates insufficient audit trails, leading to regulatory compliance blind spots and operational visibility issues.
5. Configuration-Based Security Risks Incorrect setup enables unauthorized user access. Overly permissive role mappings or unsanitized data input can provision users with excessive privileges.
6. De-Provisioning Limitations Just-in-time user provisioning focuses on account creation without automatic de-provisioning capabilities unless integrated with additional mechanisms like SCIM deactivation or IdP lifecycle rules.

FAQs
What's the Difference Between SSO and SAML?
SSO (Single Sign-On) is a login method that lets users access multiple applications using one set of credentials. This makes it convenient for users; they only need to sign in once to use all their assigned apps.
SAML (Security Assertion Markup Language) is a protocol used to securely transmit authentication and user data between systems during the SSO process. SAML is the technology that enables SSO by transferring identity information from the identity provider to the service provider.
SSO describes the login experience for users, while SAML is the protocol working behind the scenes to make that experience possible.
What is the Difference Between JIT and SCIM Provisioning?
JIT (Just-in-Time) Provisioning creates user accounts automatically during the login process, triggered by SSO protocols like SAML or OIDC. Accounts are created only when a user actually logs in, making it ideal for temporary or dynamic users. De-provisioning usually needs additional handling.
SCIM (System for Cross-domain Identity Management) Provisioning is a standard protocol that manages user accounts through the entire lifecycle, including creation, updates, and removal, using scheduled or event-based actions. SCIM provisioning offers built-in de-provisioning and more granular, proactive control over user management.
JIT is reactive and creates accounts on demand, while SCIM is proactive, managing users throughout their time in the system.
Just-in-time user provisioning suits dynamic or temporary users like external contractors, while SCIM better serves long-term users requiring full lifecycle management workflows.
