I set up an OData feed in my app and am accessing it via Excel while running locally. While the Odata feed does return data, I have the following issues: The permissions of my app are not respected, i.e. I receive data that the userid I specified in Excel should not have access to I get some error messages and suspicious looking messages in my console, specifically I receive the following messages: Login failed: No basic authentication in header. Removing session for user 'SomeUserID' Login failed: No basic authentication in header. Login failed: No basic authentication in header. Killing old session for user SomeUserID because new session is created. com.mendix.systemwideinterfaces.MendixRuntimeException: java.lang.IllegalArgumentException: Session 'f8e66053-f7da-44ac-85cb-93450e7d1870' is not managed by the session manager at com.mendix.util.classloading.Runner.doRunUsingClassLoaderOf(Runner.java:36) Caused by: java.lang.IllegalArgumentException: Session 'f8e66053-f7da-44ac-85cb-93450e7d1870' is not managed by the session manager at com.mendix.core.session.SessionManager.destroy(SessionManager.java:246) at com.mendix.core.session.SessionManager.destroy(SessionManager.java:241) at com.mendix.core.component.InternalCore.logout(InternalCore.java:2044) at com.mendix.integration.requesthandlers.RestRequestHandler.processRequest(RestRequestHandler.scala:23) at com.mendix.externalinterface.connector.MxRuntimeConnector$1.execute(MxRuntimeConnector.java:69) at com.mendix.externalinterface.connector.MxRuntimeConnector$1.execute(MxRuntimeConnector.java:66) at com.mendix.util.classloading.Runner.doRunUsingClassLoaderOf(Runner.java:32) at com.mendix.externalinterface.connector.MxRuntimeConnector.processRequest(MxRuntimeConnector.java:72) at com.mendix.core.impl.MxRuntimeImpl.processRequest(MxRuntimeImpl.java:720) at com.mendix.m2ee.appcontainer.server.handler.RuntimeHandler.handle(RuntimeHandler.java:41) at org.eclipse.jetty.server.handler.HandlerList.handle(HandlerList.java:52) at org.eclipse.jetty.server.handler.HandlerWrapper.handle(HandlerWrapper.java:116) at org.eclipse.jetty.server.Server.handle(Server.java:368) at org.eclipse.jetty.server.AbstractHttpConnection.handleRequest(AbstractHttpConnection.java:489) at org.eclipse.jetty.server.AbstractHttpConnection.headerComplete(AbstractHttpConnection.java:942) at org.eclipse.jetty.server.AbstractHttpConnection$RequestHandler.headerComplete(AbstractHttpConnection.java:1004) at org.eclipse.jetty.http.HttpParser.parseNext(HttpParser.java:640) at org.eclipse.jetty.http.HttpParser.parseAvailable(HttpParser.java:235) at org.eclipse.jetty.server.AsyncHttpConnection.handle(AsyncHttpConnection.java:82) at org.eclipse.jetty.io.nio.SelectChannelEndPoint.handle(SelectChannelEndPoint.java:628) at org.eclipse.jetty.io.nio.SelectChannelEndPoint$1.run(SelectChannelEndPoint.java:52) at org.eclipse.jetty.util.thread.QueuedThreadPool.runJob(QueuedThreadPool.java:608) at org.eclipse.jetty.util.thread.QueuedThreadPool$3.run(QueuedThreadPool.java:543) at java.lang.Thread.run(Thread.java:745) Removing session for user 'SomeUserID' Have others encountered similar issues? Any pointers about how to get OData working as it is supposed to? Thanks, Mike
