  • Patent number: 6052785
    Abstract: A system and method for managing client authorization to access remote data repositories through a middle tier server such as a web server. Client remote data repository access is intercepted by the middle tier server and the server is searched for stored credentials permitting client access to the remote data repository. If found, the stored credentials are used to authenticate access without further interaction with the client system. If no stored credentials are found, the server requests credentials from the client and passes them to the remote data repository for validation. Validated credentials are stored by the server for future use and indexed by a client identifier. Permitted remote data repository access is stored with the validated credentials. Access to a mounted remote file system is not permitted without authorization even if the remote file system would not otherwise require authorization.
