[keycloak-user] NPE in SAMLIdentityProvider

Hi all, While implementing the single logout feature, we ran into a NPE in SAMLIdentityProvider.java. This behavior seems to be independent of using backchannel logout, whether or not: at org.keycloak.broker.saml.SAMLIdentityProvider.backchannelLogout(SAMLIdentityProvider.java:154) at org.keycloak.broker.saml.SAMLIdentityProvider.keycloakInitiatedBrowserLogout(SAMLIdentityProvider.java:178) In our application we invoke httpServletRequest.logout() as suggested in the guide: https://keycloak.gitbooks.io/securing-client-applications-guide/content/t.... Version info: - ADFS server: 3.x - Keycloak server: 2.3.0.Final - Maven Keycloak modules: 2.2.1.Final We'd like to know: - Whether it is sufficient to invoke request.logout() to do a single logout - Why it is broken in the given setup I could not determine whether this is related to https://issues.jboss.org/browse/KEYCLOAK-4398 or not. Thanks & kind regards, Caroline Goovaerts Developer RIGD-LOXIA
