+# RBAC improvements in NBI with Keystone #
+ 
+## Proposer ##
+- Gerardo Garcia (Telefonica)
+- Alfonso Tierno (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).
