Consider the following scenario:
Note The correct behavior is to receive the reauthentication prompt when you resume to use OWA after you remained idle for the specified time.
This issue occurs because the idle time-out setting for public computers is handled as a session time-out.
When a public computer connects to the OWA website, they are prompted for credentials. However, the session times out after the time that is specified in the idle time-out configuration. Therefore, a new authentication is required while the connection remains active.
To resolve this issue, install the hotfix rollup package that is described in the following Microsoft Knowledge Base (KB) article:
(http://support.microsoft.com/kb/2475184/ )Description of the ISA Server 2006 hotfix package: December 2010
If a Private Computers idle time-out is needed, see hotfix 941162. The Collect additional delegation credentials in the form option must also be selected in order to enforce the Private Computers time-out. This is by design.
The script in hotfix 941162 reverses the behavior of ISA to be the same as before the hotfix and to have some UI exceptions. Additionally, you can specify a time-out for Private Computers by using the ISA Server Management console. You can still specify whether the client computer is a public computer or a private computer by using the options on the RSA SecurID form. However, these settings have no effect for Private Computers. If you reverse the effects of the script, and if you select the option that collects additional credentials, ISA uses the Private Computers time-out.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
