I've upgraded from v1.3 to v.1.4 and all went good until I replaced guacamole-auth-saml-1.3.0.jar with guacamole-auth-sso-saml-1.4.0.jar I am now stuck in a loop during the authentication process in a way that guacamole displays the message about redirecting to the authentication provider, the page refreshes ( I can see the browser address bar telling me it is reaching Azure) and it goes back to saying redirect is happening and does that all the time every time. The saml section of guacamole.properties have not been touched (obviously). Anyway I thought I'd mention it in case someone had similar issue. ...Now I was looking at enabling debug to try and understand what's going on, however placing the logback.xml file in guacamole home with the example debug configuration from https://guacamole.apache.org/doc/gug/configuring-guacamole.html does nothing at all and I can only see INFO level of messages in my catalina log file. Can you guys recommend how to successfully switch the debug on, please? Thanks in advance and keep up the good work! Cheers, Tomski
