> drop-in REST API<p>> GET /user/:user/exists<p>Wat. Use HEAD. Seriously.<p>Also, what is ":user" - how do you define the way an account is found in the tree?<p>How do you handle complex trees with potentially conflicting values for the attribute you use as 'username' ?<p>Why are their dedicated endpoints for password, expiry, enable/disable/unlock. These are all just attributes on the user object.
