Problem When SAML2 SSO Identity Partner Wants SHA-256 Authentication Requests But Weblogic Sends SHA1

(Doc ID 2386440.1)

Last updated on APRIL 14, 2018

Applies to:

Oracle WebLogic Server - Version 12.2.1.2.0 and later
Information in this document applies to any platform.

Symptoms

WLS SAML2 SSO integration is not working with ADFS acting as Identity Provider Partner (IDP) , if ADFS wants SHA-256 Signed Authentication Requests.

WLS is currently sending an authentication request in the SHA-1 format and ADFS is not accepting such, thus replying with Responder rather than providing a SAML Assertion as seen below:


Due to this issue, users cannot access Application if ADFS is configured to validate that all SAML2 Authentication requests must be signed using SAH-256
