Roles — php-opencloud 1.12.1 documentation

# Roles

A role is a personality that a user assumes when performing a specific set of operations. A role includes a set of rights and privileges. A user assuming a role inherits the rights and privileges associated with the role. A token that is issued to a user includes the list of roles the user can assume. When a user calls a service, that service determines how to interpret a user’s roles. A role that grants access to a list of operations or resources within one service may grant access to a completely different list when interpreted by a different service.
