ACD: Only one auth mechanism allowed

I’m downloading my library from ACD to my Linux box and I’m getting periodic “400 Bad Request” errors in the log.

It appears that ACD is reporting: Only one auth mechanism allowed; only the X-Amz-Algorithm query parameter, Signature query string parameter or the Authorization header should be specified.

Any idea what this means?

Apparently, I should have searched google for this error before posting… it looks like it’s been answered before.

Yes --acd-templink-threshold 0 will work around this until I fix it properly.
