Can't add user to sudoers file I'm installing Globus Toolkit . When i try to setup Certificate , this error comes : > ERROR: could not run build command: /usr/local/globus-5.0.3/sbin/gpt-build -force /home/globus/.globus/simpleCA//globus_simple_ca_2e0087ee_setup-0.20.tar.gz I think this may be due to denial of permission. I tried executing the file with 'sudo' . It says > globus is not in sudoers file . This incident will be reported I tried adding globus user to sudoers file . For your reference , /etc/group file : > sudo:x:27:globus,arul > > admin:x:1002:arul,globus (I'm using Linux Mint debian . user arul has sudo privilege . But i've to install Globus in the globus user)

After you add the user to sudoers, that user needs to log out and log back in for the changes to take effect. So, simply logging out and in should give your `globus` user sudo rights.

I'm assuming that you have the correct configuration in `/etc/sudoers`. To make `globus` a sudoer you need the line:


globus ALL=(ALL) ALL


Or you need to add `globus` to the `wheel` group and then have the line:


%wheel ALL=(ALL) ALL


Or some equivalent.
