Hi, Could someone clarify what exactly fractional replication updates are? If I e.g. change a userPassword entry for a user in my ldap directory, which is the master in a master-slave replication scenario, what gets sent to the slave? The entry for that user, or just the changed attribute, or even the entire directory? From my readings, I think that a) With Fractional Replication, only the entry gets transmitted. b) With Normal Replication, the whole entire directory gets transmitted. Is this correct? Is someone able to update the docs on this subject? The only section I can find related to Fractional Updates is here: http://directory.fedoraproject.org/wiki/Features and it is a 1 liner. Thanks, Mike
