Sync PouchDB with CouchDB server-open source projects pouchdb/pouchdb

I follow the guide getting started from getting started

For enable CORS the guide proposes this command:

    $ curl -X PUT $HOST/_config/httpd/enable_cors -d '"true"'
    $ curl -X PUT $HOST/_config/cors/origins -d '"*"'
    $ curl -X PUT $HOST/_config/cors/credentials -d '"true"'
    $ curl -X PUT $HOST/_config/cors/methods -d '"GET, PUT, POST, HEAD, DELETE"'
    $ curl -X PUT $HOST/_config/cors/headers -d \
      '"accept, authorization, content-type, origin"

But I read in the file default.ini, that I can’t set origins: * and credentials = true at the same time. In effect if I follow the above command the synchronization work well.

Why therefore default.ini say that isn’t possible set origins: * and credentials = true?
