Hello, I use a local admin account to log into the LF server. I was able to setup and run reports. I need to add someone to the permissions tab so they can run reports but I cannot. When I type in the person's name in the "Find Trustees whose names contain" i get this;

is it because I'm using a local admin and not a domain admin? And if that's the case, how can I get this person added without changing my account to a domain account? Thanks.
