How to maintaining Active Directory details in database

Team,
I need to keep all the AD details (groups,users,..etc) in my database.
One way is to create a linked server to ADS service and get the info
Is there any other way or new feature in SQL Server 2008?
Thanks & Regards

Excerpt from link below states, Active Directory can be accessed from SQLSERVER 2005 by using:

• Linked Server

• OpenRowSet

• Managed Stored Procedure

Also you can use SSIS with OLE DB Provider.
To retrieve all the users from ActiveDirectory, use the query:
"SELECT cn FROM 'LDAP://DC=DOMAINCONTROLLER,DC=local'WHERE objectClass='User'"
