Abstract: A translation gateway for a distributed computing environment including a source computer system and a target computer system, each of which has at least one client, one server and a distributed file system, and wherein the server associated with the source computer system preferably runs on a client of the target computer system. A method for providing authenticated access to files stored in the target distributed file system in response to file requests originating from clients associated with the source distributed file system begins by mapping credentials associated with incoming client requests from the source distributed file system into enhanced credentials containing authentication information associated with an authentication model of the target distributed file system. At least one enhanced credential is then augmented with one or more attributes whose values may be extracted and used in the processing of the filesystem request by the target file system.
