Rather than giving access to everyone, a more secure option would be to give the service account associated with Forms more permissions in the Security Settings of the workflow administration console.

We run our Forms instance with an AD service account, then set that account as an administrator Workflow Admin Console so it has access to all published workflows.

Since Workflow Security is not well documented - I attempted to get Laserfiche to document whether your solution was a best practice for initiating Workflow Security.  Our VAR put in a support request for this for me, but Laserfiche support couldn't find anyone at Laserfiche that knew anything more about the feature than the minimal documentation that is provided. So we ended up turning it off in our production environment as access to workflows is extremely limited.
