I've done through the following steps:
-> Open the form and select "Edit Form in Adobe LiveCycle Designer"
->File -> Form Properties -> PDF Security -> Checked "Require a password to open the document" -> Save Form
-> Reopen form
When i reopen the form, it prompts me to enter a password to enter the form.
The User can enter the form and input data but I want to protect the form when a user tries to enter into LiveCycle Designer.
Did i do the steps wrongly? Please help me? Many Thanks...
