>             Project: CouchDB
>          Issue Type: Bug
>      Security Level: public(Regular issues) 
>          Components: Database Core
>    Affects Versions: 2.0.0, 1.6.1

> This also cases annoying behaviour when `require_valid_user` set as `true`. Steps to reproduce:
> 1. Fix admin party
> 2. Create some user
> 3. Create some database
> 4. Setup members for those database excluding access for your user
> 5. Set `require_valid_user=true`
> 6. Login as the user and open up futon
> During databases list rendering Futon requests every database for the info about num of docs, db size etc. When it hits database which don't has a current user in members, CouchDB returns 401 unauthorized error, even if you are. This error comes to httpd error handler and according `require_valid_user` setting CouchDB send WWW-Authenticate header in response back to browser - this happens only for unauthorized errors. Browser sees that header and shows modal dialog to let end-user specify credentials in order to access some unnamed resource. And so happens for every database. 
> If you have hundred ones and user has access only to some single one using futon/fauxton turns into nightmare.
> The error origin from couch_db:check_is_member/1 which doesn't care about if user is already auth'ed counting everyone as not in case if they are not members.
