International Classification:

G06F 17/30

US Classification:

707009000

Abstract:

A system is presented for performing a directory operation within a distributed directory environment that includes distributed directory servers and a proxy server that acts as an intermediate agent between a client and the distributed directory environment. The proxy server sends requests to directory servers to collect information about group memberships for a user with respect to group entries within each portion of a distributed directory that is supported by each directory server. The proxy server sends the compiled information of group memberships for the user along with any directory operation that the proxy server requests on behalf of the user. A directory server receives the compiled information of group memberships along with a requested directory operation and then performs the requested directory operation with respect to its locally stored portion of the distributed directory information tree and with respect to the received information of group memberships for the user.

International Classification:

H04L 12/26

US Classification:

370230

Abstract:

A computer implemented method, apparatus, and computer program product for managing requests. Responsive to receiving a request from a client, a determination is made as to whether a connection within a pool of connections has a set of outstanding requests for the client to handle a previous request from the same client. Responsive to a determination that the connection has any outstanding request, a determination is made as to whether a set of requests queued for the connection is equal to or exceeds a threshold. Responsive to a determination that the set of outstanding requests is equal to or exceeds the threshold, subsequent requests from the client are unprocessed until the set of outstanding requests becomes less than the threshold.
