OWA 2010 - Problems with Authentication After CAS Failover RRS feed

  • Question

  • We are currently utilizing a 2 Node NLB Array for Forefront UAG.  We have an Outlook 2010 FBA Listener with a dedicated Exchagne 2010 Trunk.

    When we perform maintenance on the Exchange 2010 CAS Nodes and they go offline, the active OWA Sessions display the following message when trying to log back into OWA via UAG Application Trunk:

    "Tou have authenticated successfully using ADFS, but your username or group cannot be located in a Forefront UAG Local Group".

    We are not using ADFS, but using Authentication Servers with 2 DCs specified for Authentication.  Some other notable points about the Application are as follows:

    -2 node CAS Farm for Web Servers with Cookie Based Affinity

    -Authorize All users

    The Trunk settings have the following:

    -Inactive Session 1800 seconds

    -Automatic logoff 60 minutes

    -Delete Cookies at logoff

    It almost appears as though it is not detecting a proper logoff and cleaning up the session properly.  Anyone else ever experience this...or have any suggestions?
