E-Notebook Enterprise: Unable to Sign and Close with a password protected PDF/Word/Excel document in an experiment.

Any password protected file cannot be used inside the section type as the rendering of the experiment needs an open/active section (but not a protected/closed section).
So the solution would be using the "Link to supplementary" section type and importing any type of protected data in it.
We would suggesting this because while rendering the imported document in this section it will not be rendered as data, but it will just be shown as a link documents.

"Link to supplementary" section type is a part of SDM add-in for E-Notebook.
