Can I use useradd in SLES 11 where a username is just a number (didn't see anything in the man useradd(8) )?
useradd: Invalid account name: `9999'
The alternative is manually editing /etc/passwd, correct?
And then, what should I do to make the home directory?
Feel free to comment why this is a bad idea; because I'm unclear on that too. I'm just supporting legacy users
