Hi guys!
I need to do subj operation, without ssl and syncpass, and seems that I do everything according https://access.redhat.com/documentation/en-us/red_hat_directory_server/9.0/html/administration_guide/windows_sync-configuring_windows_sync
but no luck yet :(
Maybe someone have such experience? It this possible ever?
error.log from DS with debug mode turned on:

================

It seems like DS trying to push changes to AD (why?! I've added onewaysync 'fromwindows' attr to agreement), but even no try to pull AD tree from it...
I really need advice in it, there is no sense from google.
