New Fixes in This Release

1. When using a WinCE terminal in a session running on XenApp 5 for Windows Server 2008, insertions and removals of smart cards fail to be detected. The issue occurs when the logon process takes a long time to load and notify the credential provider of the logon event. If a predetermined wait time for the logon process is exceeded, the smart card access event is failed.

   This fix allows you to extend the logon process wait time. To enable the fix, you must create the following registry key and assign a value in the range of 4 to 10 (Decimal). Preferably, start with value of 6. Adjust this value to a higher number if smart card detection fails.
   

   HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\SmartCard
   Name: SSEEETimeout
   Type: REG_DWORD
   Data: <Range of 4-10>

   [From XAE500R01W2K8X64034][#241788]

2. Certain smart card applications might exit unexpectedly when attempting to read the smart card.

   [From XAE500R01W2K8X64034][#243347]

3. If a smart card is present in the card reader at the client device, the smart card PIN prompt can fail to appear. The issue occurs when a legal notice banner is configured and the user does not dismiss (accept) the notice within four seconds of its appearance. In such scenarios, the PIN prompt does not appear as the wait for the smart card event times out. This fix introduces support for the following registry key to extend the amount of time, in seconds, before a timeout on the smart card event occurs:

   HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\SmartCard
   Name: SSEEETimeout
   Type: REG_DWORD
   Data: <Range of 4-120 (decimal) >

   [From XAE500R01W2K8X64034][#LA0012]
