Hi, The php SAML libraries that I am using are HTTP-Redirect binding only for the single logout service. I have tried a few different configurations but I seem to be missing something with by 2.5.0-Final configuration. If I do not configure a HTTP-Post binding for the SLS, I get the error "KC-SERVICES0051: Failed to logout client, continuing: java.lang.NullPointerException". Can Keycloak support HTTP-Redirect binding for SAML logout? If so, do you know where I can get a working configuration to see what I am missing? Thanks! - Brian
