Hummm, it's quite hidden :-)

sm01@stt008:~$ grep limits.conf /etc/pam.d/*
/etc/pam.d/cron:# through /etc/security/limits.conf
/etc/pam.d/login:# Sets up user limits according to /etc/security/limits.conf
/etc/pam.d/su:# Sets up user limits, please uncomment and read /etc/security/limits.conf

It seems to be the last one ("/etc/pam.d/su").
