We are having issues managing workflows with Nintex workflows when the site in claim based.
Issue occurs when we go to Site Actions => Site Settings => Workflow Inventory. We get the prompt of access Denied.
This also occurs when we try to access the workflows from the list or library using the workflow settings on the ribbon and clicking the Manage workflows with Nintex workflows option.
The same won’t happen if there are no workflows present in the inventory.
The same will also not happen for all other Default authentication sites.
P.S.: This works with a System Account which we do not use to publish workflows.
