tlug: Changing username

[Darren Cook <darren@example.com>]

Hi,
I've a user, let's call her "fred", who wants to change name to "bob".
Redhat 6.1, with shadow passwords. No home directory, shell is /bin/false
(i.e. email-only user).

Can I just change the first field of /etc/passwd, and change the name of
her /var/mail file? Or do I have to get into messing with the shadow
password files as well?

Darren
