hi everybody,
iam using 32bit centos 6.2 on my machine, and i want to create hidden user 'test' , i mean to say while iam starting my centos at GUI mode, at that time that username 'test' should not appear at list of users, only i can use that username is command line. logging in through other username.

i have try this:

#useradd test
#passwd test
#passwd -l test

and i restart the system at that time username 'test' doen't appears but while iam trying to switch user test in command line such error occurs:
$su test
Password:
su: incorrect password

so i was not able to login. After that i know

passwd -l test = it locks the user 'test'
passwd -u test = it unlocks the user 'test'

can anybody guide me or suggest me how to create hidden account in my local machine, i'll be greatful and any kinds of ideas, suggestions and guidelines are welcome.

THANK YOU IN ADVANCE

There's nothing like hidden account in Linux/UNIX. It all depends on how GDM (if you are using GNOME) or KDM (if you are using KDE) parses the /etc/passwd and /etc/shadow files to get the list of accounts which can be used for logging in to the system.

I am unable to help you in this as I never use graphical terminals
