Xentrox

Linux centOS7 dedicated server I am attempting to add multiple administrators to our server admin list. I have tried editing the admin.xml file with the user's name and steam ID number which didnt work, i also attempted to add my own ID to the server.sh file so that i could add the others from within the game, to no avail. I have also attempted to add myself via the /admin -a command in console but it only adds to the XML file under the administrators group as name="" id="1" no matter what i type. could someone assist with this issue please
