pam_limits not effective

[Hannes Krueger]

Hi out there,

I tried to set some hard memory limits using /etc/secutity/limits.conf
I set hard limits for my user for rss, data, stack, memlock 1000
I also set a maxlogins of 4.
I added "session required pam_limits.so" to /etc/pam.d/xdm and login.

I was able to verify that the maxlogins limit works.
all other limits seem to be without effect.

Is there anything else to do?
Are there any special requirements to the kernel?

I'm using 2.6.5-7.201-default (Suse kernel)
