I have one administrator user, X, and a few normal users, A, B and C.
When logged into one of the normal users, e.g. A, and doing something system administration, e.g. opening the Software program and upgrading packages, I am presented with user X’s password input field. When user X’s password is correctly entered, the system administration operation starts and successfully finishes, under user A’s session.
This is very strange to me. Why would a normal user, not an administrator, even be presented with the option of doing system administration things?
Is there a way of changing this (very strange) default behaviour?
Thank you for your time!
