How to block sudo -i in sudoers file
 

Hi,

How to block sudo -i in sudoers file ?

Something like "user-spec host-spec = command_spec, !/usr/bin/sudo *-i*"?

I tried as user ALL=(ALL), !/usr/bin/sudo *-i* but its not working.Can you suggest any other solution ?

Please post actual output of the unprivileged user running 'sudo -l' and 'sudo -i' but do obfuscate individual entries like ", /xxx/xxx --xxx, /xxx/xxx --xx-x, " so we can have a good view of what's listed.

Actually " sudo -i " needs to be block for the users where they have sudo access but need to block sudo -i so that users can only access certain task through sudo with only their username as " sudo - <username " & not through "sudo -i" as there are many options to login through sudo.
