SSO Integration Issue – Getting HTTP 403 Error After Login Redirect in Imperva

  • 1.  SSO Integration Issue – Getting HTTP 403 Error After Login Redirect in Imperva

    Posted 5 hours ago

    Hi Everyone,

    I have configured SSO integration in Imperva DAM and the initial login flow seems to work correctly.

    However, after successful authentication via the SSO provider, when the user is redirected back to the Imperva login page, I am encountering the following error:

    Error report: HTTP 403 – Forbidden

    🔧 Setup Details:

    • SSO Type: SAML
    • Imperva Version: 14.19_50
    • Identity Provider (IdP): Accops

    🔍 Observations:

    • Authentication at IdP is successful
    • Redirect back to Imperva happens
    • Immediately after redirect → 403 error displayed

    ❓ Assistance Needed:

    What could cause a 403 error after successful SSO authentication in Imperva?
    Are there any logs or specific configurations I should verify

    Any guidance would be really helpful.

    Thanks in advance!
