This change locks and disables login access for the lpd user account. Rationale: This change disables direct local and remote login to the lpd user account. Do not set a password on this account to ensure that the only access is via su from the root account. There should not be a requirement to log in as the lpd user directly. All users should be given unique logon ids to ensure traceability and accountability.
Solution
Change the following user attributes to lpd user: chuser account_locked=true login=false rlogin=false lpd Default Value: account_locked=false login=true rlogin=true
