OWA 2010 pubslishing and Exchange 2003 legacy URL RRS feed

  • Question

  • Hi all,

    We currently have the following:

    2x UAG (non-domain), using Basic Auth

    3x Exchange CAS Servers in an array

    3x Exchange 2003 Front-Ends (using FBA and not proxied)

    My problem is with the redirection to the legacy URL. As we cannot use FBA with UAG, users are being prompted to authenticate twice - once by UAG and again by the Exchange 2003 FEs upon redirection.

    Is there any way to only prompt users once? All users internal and external are directed through the proxy, so creating an additional IIS site for FBA on the CAS servers is not really an option.

    Thanks
