UCM Content Security accounts creation through RIDC

Hi Gurus,

I have a question regarding the UCM Content Security! My req needs more granular level of security i.e document level security. I am looking at possible options with UCM Accounts / ACL security mechanisms.

Brief about REQ: User uploads docs to ADF app, and send the doc for approvals. So the doc should be accessible only to the requester and all the parties in the approval flow. Also some specific admins with the SECURITY GROUPS from Weblogic server (intern from LDAP / MICROSOFT AD provider).

We will be using RIDC to check in  & search the documents to/from UCM server. And UI is ADF application (11.1.2.4).
