Seems that modifyTimestamp of groupOfUniqueNames does not always update as it should. We have one application that updates uniqueMembers of groupOfUniqueNames groups (we have about 30000 groups, from 5 to 1000 members each). Another application syncs its sql database based on groupOfUniqueNames member's once an hour, and for speeding things up, that another application first looks from modifyTimeStamp if group has changed within last hour, and if so, it will be synced. But here is the problem: another application's database does not always sync because modifyTimestamp does not always update for some group.

Unfortunately this happens quite rarely and I cannot provide exact instructions how to reproduce this, I was not able to find any pattern either. If anyone has any ideas/experiments what is wrong/how to fix this, they are most welcome.

Are you sure that your sync process does not leave a time gap when searching for update entries? When implementing something like this I always search for entries modified after the last second before the last update. My sync processes usually generate deltas themselves anyway.
