Question #: 20
Topic #: 2
All mobile users are unable to authenticate to Prisma Access (Managed by Strata Cloud Manager) using SAML authentication through the Cloud Identity Engine. Users report that after entering their credentials on the Identity Provider (IdP) login page, they are redirected to the Prisma Access portal without successful authentication, and they receive this error message:
Error: Prisma Access Portal Authentication Failed using CIE-SAML with message "400 Bad Request" Which action will identify the root cause of this error?

Suggested Answer: C Vote an answer

The"400 Bad Request"error when attemptingSAML authenticationthrough theCloud Identity Engine (CIE)suggests amisconfiguration in the SAML metadata. This typically occurs when theendpoint URLs, certificates, or entity IDsdo not match betweenCloud Identity Engine and the IdP portal. To resolve this, verify that:
TheSAML metadatauploaded toCloud Identity Enginematches theconfiguration from the IdP.

TheACS (Assertion Consumer Service) URL, Entity ID, and certificateare correctly set.

There are no incorrect or expired certificates in theCloud Identity Engine and IdP configuration.

By ensuring theSAML metadatais properly configured inboth systems, authentication should proceed without errors.
