Siteminder IDP is receiving a signed SLO request (SAMLRequest) via POST binding, and the request is resulting in only a partial logout and an Invalid NameID error.
NameIDs are case sensitive, so the SP must preserve the case of NameID as received in the assertion when making an SLO request back to the IDP.
Release : 12.8
Component : SITEMINDER FEDERATION SECURITY SERVICES
SP needs to be configured to always preserve the case of NameID when making SLO requests to the IDP.
