In the last two or three years I worked a lot with 389 DS. I setup small installations and really big ones (more than 10.000 objects and 150 replica servers around the world). I decided to open a new page in my wiki to write down the errors and the solutios that I’ve found in this long way with DS. You can have a look here. Right now there is only one error and one solution, but I’ll try to fill it with more information gathered from my experience soon.
