I looked at the code and I believe the best solution is actually to switch the 
original approach you are referring to to this new one I'm proposing.

The entity (user/group/netgroup) in sysdb will always have only those 
attributes set by sdap_attrs_add_*. Therefore it is IMO better to delete it 
directly when preparing the replace operation instead of searching for these 
attributes afterwards. This would also mean that the flag I'm setting is 
redundant and the operation can be performed every time. Is there any case 
which I'm missing and which would make my approach unusable?

Thanks
Jan
