Password manager takes a long time to come up for users with a large number of lockbox entries.

The cause of the slowness comes down to an issue with the Unified Workspace and directory servers being out of time sync with each other.  The current UW time is used when checking the internal cache.  If the time is more than about 4 min out of sync, it can cause UW to have to refresh the internal cache with each read, significantly slowing down the process.

The fix is to make sure the time is in sync between the Directory server(s) and all the UW servers.

It should be noted that if using virtual servers, it's possible the VM environment could be trying to keep the VMs in sync, while the VM OSs try to keep themselves synced.  This can cause the various servers to drift out of sync.  It's best to have the VM environment or the OSs themselves, but not both, set to maintain the time sync.
