  • Multi-master referential integrity
    Patent number: 8583596
    Abstract: A method and apparatus for maintaining referential integrity in a plurality of directory servers is described. In one embodiment, a first directory server receives a request to operate on an entry in the first directory server. The request is serially repeated in at least one other directory server if the operation on the entry in the first directory server is not valid. The at least one other directory server communicates indirectly with the first directly server.
