+# RBAC improvements in NBI with Keystone #

+- Gerardo Garcia (Telefonica)

+- Francisco Javier Ramon (Telefonica)
+
+## Type ##
+**Feature**
+
+## Target MDG/TF ##
+NBI, OSM_client
+
+## Description ##
+The NBI module could benefit immediately of the advantages that Keystone would
+provide to support and extend its RBAC functionality. Among other aspects, the
+integration of Keystone would be expected to provide:
+- Out of the box support of different backends for user authentication: LDAP,
+Kerberos, etc.
+- Would provide a simpler mean to configure, maintain and evolve the different
+types of roles in OSM.
+- Would open the path for internal modules to leverage on its token mechanisms
+to enable or disable selectively some functionalities for a given user request.
+
+## Demo or definition of done ##
+- Authenticate NBI users against an external user directory, such as LDAP.
+- Configure some roles and check that they are applied accordingly (as
+described in the corresponding Rel THREE feature).
