AAA-AUT-0013 The user is already authenticated in all available namespaces.



User is browsing to Cognos URL and is getting the error message "AAA-AUT-0013 The user is already authenticated in all available namespaces."


Possible root cause:

  • In Cognos Configuration, the Gateway URI is configured with localhost instead of the server name
  • Cognos Application Firewall (CAF) should be set to True
  • Make sure namespace bind credentials are correct
  • Check namespace "Selectable for authentication?" property is set to True

Resolving The Problem

Launch Cognos configuration, Stop IBM Cognos Service and perform the following steps:

  1. Modify the gateway URI, Dispatcher URI and content manager URI from localhost to actual server name (or IP address, or FQDN)
  2. Set the IBM Cognos Application Firewall to True
  3. Test all the namespaces and make sure all test successfully. (if these fail then make sure bind credential for the namespace are set correctly)
  4. In the namespace, make sure selectable for authentication is set to True.
Save, start the IBM Cognos Service
