Identity Data Anywhere


Virtual Identity Server (VIS) is a.NET LDAP Virtual Directory that provides a single, real-time view of identity data from any data store.


About Our VIS Federation Services

Virtual Identity Server (VIS)


.NET LDAP Virtual Directory

Most companies have multiple directory services deployed in their environments, such as multiple AD forests and domains. While this is a sound operational practice, it results in user identity information being scattered across separate directory repositories. This poses a significant challenge when attempting to deploy enterprise applications to the users existing in these directories.

VIS is an LDAP virtual directory server that solves this by providing a single joined view of data from these separate directories. Applications connect to the VIS exactly as they do any normal LDAP directory. In fact, to the LDAP-enabled client application, VIS looks and behaves just like a standard Active Directory or ADAM server. The key benefit is that it allows multiple directories to be joined in real-time, without the need to duplicate LDAP objects.

Virtual Identity Server can also join and merge data coming from other LDAP directories (such as eDirectory, Sun), as well as from SQL databases (such as Microsoft SQL Server, Oracle). To the calling application, the interface functions as one LDAP directory (VIS). In reality, data is being joined and merged in real-time from multiple disparate data stores.

Built on Microsoft technology for Microsoft technology

Virtual Identity Server (VIS) was written from the ground up to tightly integrate with Active Directory and leverage the existing investment that was made in the Microsoft infrastructure. VIS was written entirely in Microsoft .NET managed code and seamlessly integrates and extends the functionality of Active Directory, providing the necessary virtual directory/proxy and LDAP firewall needs for corporations.

The Virtual Identity Server (VIS) utilizes adapters to connect to and integrate with LDAP directories, databases and other data stores. These adapters handle connecting to and communicating with the given data repository.

Now, utilizing the Virtual Identity Server your LDAP enabled applications have access to data that resides anywhere within your enterprise, regardless of the data format (i.e. SQL/LDAP). The Virtual Identity Server handles all of the data transformation from one data storage type to another. This is performed on-the-fly and in real-time. When the application queries the Virtual Identity Server, that query is translated and then proxied to the appropriate downstream data store.
