login.conf limits

[Kövesdán Gábor]

Hello,

I've been using FreeBSD 5.3-RELEASE on a production machine, but now I 
have some problem with my users. One of them isn't an experienced 
FreeBSD user, and accidentally started 19 instances of the same program, 
and these instances crashed in the background and produced a load 
average about 20. It is a small server with trusted users, but I'd like 
to avoid such issues, so I decided to make a strong limit for the users 
in login.conf.

I've read the documentation and login.conf(5), but I haven't read what 
to do when I redefine the default class. Should I delete and recreate my 
users or the new settings will take effect without doing that? The class 
identifier is stored when I create an account or the settings the class 
name refers?

Cheers,
