Nesta exceção, nós incluímos os escopos necessários (se houver algum) como uma string separada por espaços (utilizando `scope_str`). Nós colocamos esta string contendo os escopos no cabeçalho `WWW-Authenticate` (isso é parte da especificação).

developing Gradle. By default, the build is [configured](https://github.com/gradle/gradle-org-conventions-plugin#what-it-does) to use the build cache node in the EU region.

The build cache has anonymous read access, so you don't need to authenticate in order to use it. You can use a different build cache node by specifying `-Ddevelocity.edge.discovery=false -DcacheNode=us` for a build cache node in the US or `-Ddevelocity.edge.discovery=false -DcacheNode=au` for a build cache node in Australia....

**Note that by default no policy is set on a user**. Thus even if they successfully authenticate with AD/LDAP credentials, they have no access to object storage as the default access policy is to deny all access.
