We were planning to leverage WS_EAF for our authentication using SAML. Unfortunately PEWS does not support WS-EAF(as per documentation - http://pic.dhe.ibm.com/infocenter/p8docs/v5r0m0/index.jsp?topic=%2Fcom.ibm.p8.security.doc%2Fp8psn040.htm).
We have a .NET front-end which typically passes SAML tokens to services. With PEWS we thought we could do the same. Any recommendations are welcome.
