Hey Aci,
It looks like that was a bug. The Security tag was being parsed correctly, but was not being added to the formatted output. This has been fixed for the next
beta (which should be Wednesday). I don’t see you in any of the Toad for Oracle beta discussions. If you’re not already on the beta program, you can download the latest beta here.
Here you’ll be able to get a snapshot of the latest development effort, including new features and any bug fixes. You’ll also be able to be part of the development
process by providing direct feedback on new features as they’re being added and help shape Toad into how it would work best for you and other users.
In the meanwhile, you may have to add the entry manually outside of Toad’s TNS Names editor.
Thanks for bringing this issue to our attention! Feel free to let me know if you have any questions.
Thanks!
-John
