Default Adding user's and groups

Is it ok to edit the /etc/passwd and /etc/group files
manually to add users and groups or would this circumvent other required system
commands from being executed when adding them at the command line via useradd
and groupadd?

In reading the docs @ http://www.centos.org/docs/5/html/Deployment_Guide-en-US/s1-users-tools.html#s2-users-cmd-line
I see a user that is created with these utilities is disabled until unlocked
with passwd. If someone is creating users for services without home dirs and
shell access, how do you handle the password? Looking at the example provided
in a doc I am reading, there is β€œ*” in the password field in the
passwd file. Is that suggesting it’s just not displayed in the doc, or
does the β€œ*” have specific meaning?

Thanks!

the useradd/mod/del and passwd commands will work with any supported
PAM, while manually editing /etc/passwd and /etc/shadow will only work
if you're using the default authentication methods.



re: the *, see `man 5 passwd`

edit passwd and group is enough but if you need home dir, you need to
create it manualy, chmod and chown it

with
# passwd username

*, mean you can not login as this user (their is no password). Anyway
you can still
# su username
if you are root because root dont need to provide a password to
impersonate another user

Alain and John,
Thanks! The man didn't provide this last bit of info! So no password makes since as I have not come across any docs when installing daemons that indicate where to provide the password!

Thank you both,
