We are using "become username" to login as another user (ex. become root) and i think it is using su to login in that username.
I want to block a particular user account home directory where all the important files are located. I tried to change the password. After changing password,i am
able to login as that particular user. Eventhough 'become user" also working to login as that user. i want to restrict that to prevent any unnecessary actions.
Can anybody help me out on this issue?
