Abstract
In a directory service, a sync request requesting changes to a dataset is received from a sync client, the sync request comprising a token, and sync requests containing tokens are sent to first and second directory servers. Changes are returned by the directory servers with tokens, and the changes are returned to the sync client with a unified token. In embodiments, the changes returned to the sync client are new to the sync client. Also disclosed is a method where a request for new changes to a dataset is received from a sync client, the request including a token, and a response that contains a token and changes that are new to the sync client is returned.
Claims18
A method of synchronizing changes in a directory service comprising a proxy server coupled to a first and second directory server, comprising:
- (a) the proxy server receiving from a sync client an initial sync request, the initial sync request comprising an initial sync request parameter and an initial token, wherein the proxy server sends a sequence of sync requests to directory servers, and wherein the sequence of sync requests includes a first sync request and a second sync request;
- (b) sending to the first directory server the first sync request to return changes previously made to a dataset, the first sync request comprising a first sync request parameter and a first token;
- (c) receiving a first response from the first directory server, wherein the first response responds to the first sync request and comprises a first directory change set and a first response token, wherein the first directory change set comprises one or more changes to the dataset;
- (d) sending to the second directory server the second sync request to return changes previously made to a dataset, the second sync request comprising a second sync request parameter and a second token;
- (e) receiving a second response from the second directory server, wherein the second response responds to the second sync request and comprises a second directory change set and a second response token, wherein the second directory change set comprises one or more changes to the dataset and the changes in the first directory change set and the second directory change set together satisfy the initial sync request parameter;
- and
- (f) the proxy server receiving from the sync client a subsequent sync request, the subsequent sync request comprising a subsequent sync request parameter and subsequent token,
- wherein the initial token comprises indicia of first previous dataset changes and indicia of second previous dataset changes.
