Fixed In Version:	openstack-keystone-2015.1.0-1.el7ost	Doc Type:	Enhancement
Doc Text:	The Identity service now allows restriction of re-scoping tokens to only allow unscoped changes to be exchanged for scoped tokens. The Identity service allows for an existing token to be used to obtain a new token via the 'token' authentication method. Previously, a user with a valid token scoped for a project could use that token to obtain another token for a different project that they were authorized for. This allowed for anyone possessing a user's token to have access to any project the user has access to, as opposed to only having access to the project that the token is scoped for. To improve the security properties of scoped tokens, it was desirable to not allow this. A new 'allow_rescope_scoped_token' configuration option is available to allow token rescoping to be retricted. Rescoping of tokens is now only allowed by using an unscoped token to authenticate when this option is enabled.	Story Points:	---
