You only have one commit incorrectly signed off! To fix, first ensure you have a local copy of your branch by [checking out the pull request locally via command line](https://help.github.com/en/github/collaborating-with-issues-and-pull-requests/checking-out-pull-requests-locally). Next, head to your local branch and run: ```bash git commit --amend --no-edit --signoff ``` Now your commits will have your sign off. Next run ```bash git push --force-with-lease origin kerberos-auth-proxy ``` Commit sha: [646dfbc](https://github.com/databricks/databricks-sql-python/pull/660/commits/646dfbcf4bce7ec031d6cd7aeceef4cf445803b7), Author: Jade Wang, Committer: Jade Wang; The sign-off is missing.
