Force users to log in as named users

[Angela Swyers_1]

I want to force my users to log in as named users instead of using generic accounts. We need to have account like 'oracle' that you need to be logged in as to run certain procedures, but I want to force them to use the 'su' command so there is an audit. How do I do this? This is not a trusted system.

check $(who -Rm |awk '{print $1}') against the generic account name like oracle.

So if the output for the above is oracle, then exit shell.

You can make this with /etc/profile to check the $USER or $LOGNAME to match with generic accounts as like oracle.

if [[ $USER = "oracle" ]]
then
echo "Don't login as generic account"
sleep 1
exit 1
fi

You can use arrays to manipulate multiple generic accounts.
