Apologies in advance if this is in the wrong section, I don’t post on here very much.
So I’m trying to make a script that executes a command of “‘add_principal identifer.’ …identifiers…‘group.admin’”
I added add_ace resource.resourcenamehere command.add_principal allow into the server.cfg but I still continue to get the error “Access denied for command add_principle”
Just out of curiousity I ran this command in the console with this output and I’m completely clueless as to why its not working. 
If anyone is willing to help and needs more info I’ll gladly do whatever to get it to work. Thanks in advance!
