On linux mint mate 17.2, oracle-xe created a user oracle with uid = 1001, its password part in /etc/shadow is *, which means disable for login I guess.
But the user oracle still shows in the login screen.
I have tried to lock the user for login via passwd -l oracle, but it still shows on login screen.
The questions are:
- What kind of user is shown on login screen? Is that users with
uid >= 1000? - How can I keep the user (with uid >= 1000), and stop it from shown in login screen?
