anyone here successfully using leiningen with AWS multifactor auth

I'm trying to use [s3-wagon-private "1.3.1"] and it's calculating invalid signatures on the s3 requests

lein seems to remember that I tried lein upgrade but it didn't complete, because now even if I say lein version, or lein clean, the downloading re-commences. I'm on a poor Internet connection at the moment. Is there any way stop this downloading behaviour?

@arthur haven't used it with multifactor auth before, does that have an impact on your access keys?

yes it adds a third value AWS_SESSION_TOKEN that is also part of the credentials
