I saw the following thread and though it was going to be the answer.

Unfortunately, it is not. These lockouts are occurring on a regular basis now, and is causing management to reconsider using seperate Vault IDs. (which would be a big pain for both IT and users who have to remember yet another set of credentials) The common intigating factor seems to be the client being left open and allowed to time out. Then, the user clicking in the interface a few times (like on Saved Searches) before receiving a notification that they have been logged out. (why doesn't the client just log itself out?)
Earlier today, a user had Vault client and a checked out Word document open. Vault locked him out while he was AFK, and when he returned, he had been locked out of AD. When I unlocked his AD account the Vault client let him in, but Word would NOT. Every time he tried to log back into Vault through word (while he had an operating Vault cleint open) it would instantly lock out is AD account again.
What's going on here? If I can tweak Group Policy to reduce the occurance of this I will, but it seems that vault makes multiple retries when it should know better. As a data point, so far this error is only occurring on machines with Autodesk CAD products installed. machines with only vault haven't noticed this error yet. (it hasn't been thouroughly tested however)
(Vault Server is SP2 and all clients are all SP2 with the AD fix and TS1110607 installed)
