Hi all, anyone seen anything like this? We're using Wyse 3040s on ThinOS 9.1.3129 and have had this issue since we started with 9.1.1131. Our terminals are configured with WMS to point to a Citrix storefront. Our default domain policy has AD accounts configured to lock after 3 bad password attempts.

The scenario:

-a user enters an incorrect password on their thin client just once.

-Security logs on the domain controllers show three "kerberos pre-authentication failed" events (event ID 4771) originating from the Citrix Storefront server followed by "a user account is locked out" event (event ID 4740) all within the space of one second.

-Citrix Delivery Services logs on that storefront server show "an authentication attempt was made for user: that resulted in: Failed (Windows Error Code: 1326" three times in the space of one second, this suggested it is receiving these attempts from the thin client one after the other very rapidly and more quickly than a user could ever type them.

-the user cannot attempt to enter their password again, their AD account is locked and has to be unlocked by our helpdesk.

-Testing the same citrix storefront via a web browser shows normal behaviour, again suggesting the thin client is the problem

Hoping someone can shed some light on this because our users are getting quite annoyed!

Thanks
