By default, SAFR Server creates a user called "safr" at installation and SAFR Server is run as this user. If you want to perform SAFR commands or view files in the SAFR directory, you should either use sudo on each command or change to the "safr" user by using "sudo su safr -" before running server commands. If you want, you can change the user that SAFR installs under using the -u option on the installer command line.
