How do we configure auth so that only one user can write to a branch? In AWS, we would set a bucket resource policy to deny everyone except one user, but I don't think there are resource policies in Lakefs.

Would we configure a user policy for everyone with write permission to every branch except that one branch? Is the "except" syntax supported by lakefs?

Hi Sid, 
Does that help? You can use “deny” - IAM syntax.
