I think this is related with SAM-2535, but If we ignore any author set by the user, why don't we just remove the author box? If the user can set the author
in the template but we don't allow him, he will think it is an error.
To reproduce this:
- Create or edit a template.
- Set the author, no matter what value.
- Save the template.
- Edit the template. The author is empty.
