Users are unable to publish workflows. They can create and save them, but when going to publish them they are either getting an error message saying that they don't have permission or they are getting a pop-up continually asking for their credentials. When they cancel out of the pop-up, they are getting a 401 error. When I checked the ULS logs it says that they don't have a windows identity. Claims to windows token service is running just fine. I as a site collection/farm admin am able to publish workflows. I'm sure I'm overlooking something simple, but I can't seem to track it down.
Try going to the Site Settings and clicking on the "Allowed workflow designers" link in the Nintex Workflow section. Make sure the users have the appropriate permissions there and are not excluded. By the default, these permissions inherit from the parent site permissions.
I don't know if it is your case, but take a look at this >>> Workflow Failed to Run or Failed to Publish Workflow, after applying Microsoft Update - Nintex Knowl...
Thanks, but I don't think this is the problem. I applied the fix before applying that patch and workflows are now running. Also, I can still publish workflows.
These seem to be telling me the same thing. That the approved workflow designers should be inheriting permissions (which it is) and that users must have sufficient privileges (they have full control). The last post didn't seem to have a resolution. I'm still stuck.
