Adding or Removing Athena Users

• If you forgot to do so when installing,

  cp /etc/passwd /etc/passwd.local
  cp /etc/group /etc/group.local
  

  and remove entries from the local files corresponding to Athena users and groups which should not normally exist on your system. A lot of software breaks if /etc/passwd isn't world-readable, so you should run

  chmod a+r /etc/passwd* /etc/group*
  

  afterward to be safe.
• To add an Athena user (thus allowing that user to log in remotely to your system if you've enabled remote access; you'll probably want to do this for yourself):

  hesinfo username passwd >> /etc/passwd.local
  

  (Be sure to type both greater-than signs.)
• To remove an Athena user, remove the line mentioning that user from /etc/passwd.local, chmod a+r /etc/passwd*, and run /etc/athena/reactivate.
