Optimal IdM, a provider of identity management software and consulting services, has announced an enhanced edition of its Virtual Identity Server for SharePoint.

Virtual Identity Server for SharePoint (VIS for SharePoint) now includes an advanced cross-forest windows authentication module. This module leverages a user’s existing Active Directory credentials, providing a seamless multi-forest single sign-on system without requiring forest trusts, said Optimal IdM.

Users who are logged into an Active Directory domain are automatically authenticated to SharePoint when accessing the site. Users who have not authenticated to an Active Directory domain are prompted for a user id and password. This enables organizations to deploy one instance of SharePoint to external and internal users without creating a forest trust or requiring internal users to re-authenticate, noted Optimal IdM.

It is reported that VIS for SharePoint also simplifies the security within SharePoint by providing administrators a dynamic role-based access control security model for SharePoint. Administrators are no longer required to manage security and group membership on an ongoing basis.

Larry Aucoin, managing partner of Optimal IdM, said: Our VIS for SharePoint solution now provides organizations with the ability to establish access based on business rules that dynamically manage security within SharePoint. In addition, VIS for SharePoint allows for virtual static groups to have members that span multiple Active Directory forests without the need for trusts.
