Ctreating Users

I was wondering if it was possible to create user accounts that begin with a number.
ex. 37ffw7523

I'm running Solaris 8 and need these accounts for an ftp server. I am able to creat regular user accounts and use an alias to get it to work...I was just wondering if there was a way to do it without using alias'.

What happens if you create them? Do they work? Do you get an error message?

The error I get when I create a user that begins with a numeric value is something like this:
UX: useradd: 123abc name first character should be alphabetic

Is there somewhere where I can change this to allow the first character to be numeric.

You could always bypass the useradd command and add the users to /etc/passwd, /etc/group, /etc/shadow, etc by hand. If the useradd command complains about the first character being a number there may be a good reason for it, so bypass it at your own risk.
