I have a user who has had his single computer require re-entering his key about 6 or so times at this point, and I have already set his fingerprint matching to loose. Is there anything you can do from your side to diagnose what might be causing this? He said that in the most recent case, it appeared to correlate with clearing the cache on his browser. PM or email me if you need specific information about his user id, log info, or anything else I can provide.
I have about 5500 keys deployed, and there are probably 2, maybe 3 users in total who have this issue, but this one is the worst, and seems to be the most random - the others all seem to be “I added a hard drive, renamed my machine, …” so those make more sense to me.
