Documents and Media supports adding external repositories such as Alfreso, Documentum, Sharpeoint, etc. 

However, it doesn't provide an API as a mechanism to authorize users from the external repository.

This task is to allow Documents and Media to delegate the authorization of external repositories to a custom implementation. This will be implemented using Capabilities so each repository implementation can decide whether it supports a custom authorization or not.
