How could I have dropped out of sudoers? [duplicate]

  • 772

I started to receive a message 

dims is not in the sudoers file.  This incident will be reported.

about myself.

How could this happen?

The suspicious command I made was creating group "advanced" and adding myself to it.

addgroup advanced
usermod -G advanced dims

Could this break my sudo rights?

sudo

    After

    usermod -G advanced dims

    the user dims is only a member of the group advanced but not of any other group. So as he isn't a member of the group admin or sudo he is no longer allowed to use sudo.

    To just add a user to another group you need to use the -a switch to usermod, like

    usermod -a -G advanced dims
