I think I might be suffering from the same issue the REST API Doc says the following. "The API is available to Superuser and Superuser (readonly) administrators from PAN-OS 4.1.0;" This suggest to me that the superuser (readonly) account should get access to commands exposed via the API.
However if i try to run say https://<firewall>/api/?type=op&cmd=<show><arp>all</arp></show>&key=<keyvalue> i get invalid credentials yet the CLI for PAN OS 4.1 document suggest that the follwing user account types should be able to run this command "superuser, vsysadmin, deviceadmin, superreader, vsysreader"
I would rather not have to use a full admin account to get access to simple show commands for the device anybody have any ideas.
