Symptoms

When the BIG-IP system is used as Service Provider with SimpleSAMLphp as Identity Provider, processing of signed artifact response messages from IdP may fail with following error: Digest of SignedInfo mismatch.

Impact

User SSO may not work.

Conditions

- BIG-IP system is configured as SP. - Artifact binding is used for SSO. - Artifact response message from IdP is signed.

Workaround

Use POST binding instead of Artifact.

Fix Information

The BIG-IP system configured as SAML Service Provider can now correctly process messages from SimpleSAMLphp so that user SSL works as expected.
