Abstract
The invention is a system and method for ensuring that a storage virtualization system performs as a trusted delegate for a user attempting to access data on an authenticated server. Data is moved from a first server to a second server by a storage virtualization system. Even though the user may have been authenticated to access the first server, the storage virtualization system which re-directs user requests to the migrated data on the second server may not be authenticated. The first time a user is re-directed to the second server, the storage virtualization system will obtain request to act as a trusted delegate for the user by communicating with a third server, such as a Kerberos domain controller. After the storage virtualization system is properly authenticated as a trusted delegate for the user, future re-directed requests will be seamless and transparent to the user.
