problems in creating new users

Waqar Razi — Wed, 17 Jun 2009 13:12:31 GMT

I am trying to create new users using useradd command but having the following error:

useradd cannot lock shadow password file

We are using RED HAt Entrerprise 4.

Shalom,

There may be a vi or other hung hession on the file.

Best bet is to look at the process list, kill the process and try again.

It could be a hung useradd command. Could also be no space on the root file system.

A reboot will also fix the problem. Clumsily.

Check if you have the /etc/passwd.lock file. Verify it's contents.

How many users (lines) do you have in the /etc/passwd file?

Hi,
Using fuser command you can find any attached process to your shadow file.
you can refer to the man page for fuser to get an idea about how can this fuser command can help you to solve your problem.

Good Luck...!
