The imprecise caching of directory download responses for dynamic directory services is disclosed. A server maintains a dynamic directory service of a plurality of clients, and an imprecise cache of directory download responses to directory download requests provided by the clients. When the server receives a new directory download request, it first searches whether an equivalent server response is stored in the imprecise cache. If there is such a response, it is returned to the client generating the request. This saves the server from having to traverse the entire dynamic directory to respond to the request. The cached responses are desirably expirable, so that accuracy of the responses is not overly sacrificed. The responses expire according to their lifetime, which is desirably adjusted based on server workload.
