newbie question: logins command

[cokster]

I ran a logins -x -o command on a HP-UX 11i box and found that a lot of users have *NP* in the passwd field. I'm just wondering this means that:
1) these users don't need a passwd to login; or
2) no passwds are valid, users cannot logon to this accounts

I think the latter is the case. Then how do I know whether which users do not need a passwd to login? e.g., by looking at :: in the /etc/shadow?? Or HP-UX 11 by default does not allow a user to login without a password?

NP means "no password".
See man logins for details.

NP stands for No password.. It's not good to have setup like that.
Convert system to trusted so you can have more controls on password and user accounts.

The former is the case - the users can login without password.

It all depends on the PAM module. You have to configure /etc/pam.conf and /etc/pam_user.conf to do this.
