What tabs do you have for your DNS server?

"Control Lists" and "Advanced" in addition to what you have.

I have generated a key in "All Zones", but I do not see it in the Key List.
what coud be wrong?

Does the corresponding eDir object exist? Is it replicated properly?

Which codebase are you running on (OES2015SP1, ....)? And which build of the java console?
