Hello,

if you don't have access to the AD server logs it will be a bit challenging to identify the real reason the server closed the connection on you. We've had the same problem with a customer once - the admins wouldn't investigate / give us logs to work with as they claimed the problem had to be on our end since their own test app worked fine, and the LDAP-AD synchronization would fail once every couple of hours (we actually set it to run every two hours to have a chance to at least have one successfull synchronization per day).
I'd try to work with the batch sizes as I've encountered some AD configurations / setups that had problems handling larger sets of data, especially if the customer added a lot of custom data fields per record or maintained insanely huge group membership structures. So lowering

queryBatchSize‍

attributeBatchSize‍

would be my personal first attempt to isolate the problem.

Regards
Axel

Thank you Axel.

I have tried to set theses attributes to 500 instead of 1000 (queryBatchSize or attributeBatchSize) but the problem is still here.
I will ask about AD logs details to continue…

take a look at my howto, it covers ldap, and it's what we currently use in our environment, works flawlessly.
