problem with ulimit

[Hugh Caley]

I'm trying to allow users on the machine to save core.  I get the 
following error:

-bash: ulimit: core file size: cannot modify limit: Operation not permitted

So I modified /etc/security/limits.conf by adding the following line:

*                hard    core            1000000

(also tried unlimited in the last field)

but it doesn't seem to make any difference.  Am I getting the syntax wrong?

Hugh
