Document Security Administration Guide

# Introduction

OmniGroupServer is a generic group server that collects user and group security information from many types of repository.

OmniGroupServer can retrieve information from:

- Active Directory
- Documentum
- LDAP
- IBM/Lotus Notes
- Microsoft NT (though OpenText recommends retrieving these groups through LDAP).
- Netware
- SharePoint (SharePoint uses a combination of SharePoint and NT security, so in addition to retrieving the SharePoint groups you must also retrieve NT groups through LDAP. For more information about setting up mapped security for documents retrieved from SharePoint, refer to the Help for your SharePoint Connector).
- Text files

OmniGroupServer stores the collected security information and checks for updates at regular intervals.

When a user starts a session with a Knowledge Discovery front-end, the client application requests security information from the Community component. Community retrieves the user’s security details from OmniGroupServer and returns the information to the application. The client application then adds the security information to every subsequent query it sends to the Content component. Content can then compare the user’s security details to a document’s access control list (ACL) to determine whether to grant access to the document.
