I'm trying to commit a CL using "git cl land".  The test image is too large to upload (https://codereview.chromium.org/2482883002/).

I've set my "git config user.email" to msarett@chromium.org and I've also logged in as msarett@chromium.org using "depot-tools-auth login https://codereview.chromium.org".

I'm getting this error:
msarett@msarett1:/usr/local/google/chromium/src$ git cl land
Using 50% similarity for rename/copy detection. Override with --similarity.

Any idea what I need to to authenticate myself?
