WebLogic Server Service Provider with HTTP Redirect Binding Requests Fail with "get SAMLRequest from http request" and "can't unmarshall to a saml object"
(Doc ID 1405215.1)

Applies to:Oracle WebLogic Server - Version 10.3.3 and later
Information in this document applies to any platform.
When using SAML 2.0 with HTTP redirect binding, WebLogic Server encounters an issue with inflate/deflate. The WebLogic Server Identity Provider (IdP) gives the same error with every authorization request.
WebLogic is configured as the IdP, and a simple PHP Service Provider (SP) is to be configured. There was no resolution after trying three different PHP libraries (SimpleSAMLPPHP, Apache mod_auth_mellon, Lasso).
