[Samba] Bi-directional sync for Sysvol folder -- Osync?
Hello Min Wai Chan, ? Can you explain more about,, the DC1 will remove any emptey directory on DC1. tested it here, but that does not occure here. i can create empty directories on DC1, and these are synced to DC2. empty or not. ? ?DC1 will overwrite any users/group change on DC2? if setup correctly, your sysvol rights on DC1 and DC2 are the same.. ? i suggest you to the following. get the latest version of the script. stop samba on both dcs. copy idmap from DC1 to DC2, and start up again. these last steps are in the latest?script also. ? Greetz, ? Louis ? ?

Dear Belle, I think I'm using the 1.02 Version as we post question on Feb. But I don't think there are much different At least when I see from the cron script and also the unison default.prf I think this script have 2 major issue. 1. DC1 will Remove any empty directory on DC1 2. DC1 will overwrite any users/group change on DC2? the last issue I see is that cron.d are sending mail every 5 mins..(but I think that can be solved) I've not try osync before... but it look promising...
