change maximum number of open files for user on solaris 9

Question

i need to change ulimit -n for the user permanently, on solaris 10 you can do projadd -K "process.max-file-descriptor=(basic,8192,deny)" proj.files but on solaris 9 projadd or projmod doesn't have -K key. Adding proj.files:100::::process.max-file-descriptor=(basic,8192,deny) to /etc/project doesn't help either.
