Thx for pointing me to this multi-edit via batch operation.
It's still not working for me: Online Execution is greyed out - only ldif creation is selectable (OpenDJ 2.4.3)
(Yes I've write permissions with the account connected..)
In the batch dialog I've to select the action "add" or "replace" for an attribute.
Should a mixed edit of an attribute which is already existent in some of the entries work with batch operation whren I select replace - or is this a fire and forget ldif action?
Hint for others: Multiple entry selection has to be done in the left pane (e.g.) search results
Wish: Entries should be selectable also in the right pane, because there - you can sort and select by additional attributes other than the "dn"
My comments reflect v1.5.3
