SAML Single Sign On or Single Logout to support HTTP-Redirect Binding

Liberty seems to only support HTTP-POST binding for SAML Login and Logout based on our investigation

<md:SingleLogoutService
                       Binding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST"
                       Location="https://......." />
We have configured our applications (RP) with Liberty OP which is further delegated to a SAML IDP.
https://www.ibm.com/docs/en/was-liberty/nd?topic=liberty-configuring-saml-web-browser-sso-in

For the SAML IdPs where the metadata contains SingleLogoutService HTTP-POST binding , the logout works fine.

MS Azure SAML IDP only supports HTTP-Redirect at this time and customers using Azure have no option to enable HTTP-Post.

    Thank you for the suggestion. The requirement does have merit, but looking at it with respect to our total backlog of requests we do not see sufficient interest in this enhancement to merit delivery any time in the foreseeable future. Given the unlikelihood that we would deliver this, we are declining the request rather than leaving it in an uncommitted state for an extended period of time. If you would like to discuss this decision further, please contact Chloe Macdonald <chloe.macdonald@ibm.com>
