Artifactory SAML SSO Session Invalidation
When using SAML Single Sign-On (SSO) with Artifactory, session management and invalidation are critical for maintaining security, especially when users log out from the identity provider (IdP). Here's a detailed guide on how to handle SAML SSO session invalidation in Artifactory.
Understanding SAML SSO Session Invalidation
When a user logs out from the IdP, the SAML session should be invalidated in Artifactory to prevent unauthorized access. This involves ensuring that the SAML session is correctly invalidated or timed out. Here’s how to manage this process effectively:
Prerequisites
Artifactory Version: Ensure you are using a version of Artifactory that supports SAML authentication.
Identity Provider Configuration: Have your IdP (e.g., Okta, Azure AD, ADFS) set up and configured for SAML SSO.
Steps to Configure SAML SSO Session Invalidation
1. Configure SAML Settings in Artifactory
Navigate to Admin > Security > SAML in the Artifactory UI to configure the SAML settings.
Issuer URL: Set this to the SAML issuer URL provided by your IdP.
SAML Service Provider Entity ID: Typically, this is your Artifactory URL.
Assertion Consumer Service (ACS) URL: Set this to the URL provided by Artifactory.
2. Set Up Single Logout (SLO)
To ensure sessions are invalidated upon logout, configure Single Logout (SLO) in both Artifactory and the IdP:
Artifactory Configuration:
Enable SLO in the SAML settings.
Specify the SLO URL provided by the IdP. This is typically something like
https://<artifactory-domain>/artifactory/saml/SSOService.
Identity Provider Configuration:
Configure SLO URLs in your IdP settings.
Ensure the IdP sends a logout request to Artifactory at the specified SLO URL.
3. Update IdP Settings for SAML SSO
Ensure the following settings are configured in your IdP:
Single Logout URL: Configure the SLO URL in the IdP settings.
Logout Response: Ensure the IdP sends a logout response to Artifactory.
4. Test the SAML SSO Session Invalidation
Logout from the IdP: Log out from the identity provider and verify that the session is invalidated in Artifactory.
Check Artifactory Session: Attempt to access Artifactory after logout to ensure the session is terminated and the user is redirected to the login page.
5. Configure Session Timeout Settings in Artifactory
Adjust the session timeout settings in Artifactory to ensure sessions expire after a period of inactivity:
Navigate to Admin > Security > Session Management.
Set the session timeout value according to your security requirements.
