[keycloak-user] Tomcat SAML Client adapter and infinite redirect

Hello everybody. I'm trying to set up Tomcat <-> Keycloak SAML integration. I've got stuck with the infinite redirect issue: after successful authentication I'm returned back to Tomcat Web app (to its protected resource) and then redirected back to keycloak with message YOU ARE ALREADY LOGGED IN. Keycloak 3.4.3 Tomcat 8 The problem is practically the same as described: https://stackoverflow.com/questions/43452853/unable-to-redirect-to-my-tom... The problem is reproduced when I try to load http://localhost:8080/lr/protected (the web application is attached). Thanks for every advice!
