검증

1. idmclient 호스트에 idm _user 계정으로 로그인합니다.

2. 새 sudo 규칙을 테스트합니다.

   1. idm_user 계정이 수행할 수 있는 sudo 규칙을 표시합니다.

      [idm_user@idmclient ~]$ sudo -l
      Matching Defaults entries for idm_user@idm.example.com on idmclient:
          !visiblepw, always_set_home, match_group_by_gid, always_query_group_plugin,
          env_reset, env_keep="COLORS DISPLAY HOSTNAME HISTSIZE KDEDIR LS_COLORS",
          env_keep+="MAIL PS1 PS2 QTDIR USERNAME LANG LC_ADDRESS LC_CTYPE",
          env_keep+="LC_COLLATE LC_IDENTIFICATION LC_MEASUREMENT LC_MESSAGES",
          env_keep+="LC_MONETARY LC_NAME LC_NUMERIC LC_PAPER LC_TELEPHONE",
          env_keep+="LC_TIME LC_ALL LANGUAGE LINGUAS _XKB_CHARSET XAUTHORITY KRB5CCNAME",
          secure_path=/sbin\:/bin\:/usr/sbin\:/usr/bin
      
      User idm_user@idm.example.com may run the following commands on idmclient:
          (thirdpartyapp) /opt/third-party-app/bin/report
