Changing ulimit for all users not working as documented

Linux Version 2.6.39-400.17.1.el6uek.x86_64  (6 U 4)

All documentation I have found suggests that I should add a line to /etc/security/limits.conf like:
* <space> soft <space> nofile <space> 20480  <---editted 9/26/13....'nofile' rather than 'nfile'
and reboot.

When I sign on as a non-root user and execute # ulimit -n
the response is 4096  (prior to adding this line the value was 1024)

There must be a ceiling value somewhere. Where?  I have an application to install on this server that has a requirement to set the soft nproc value to 20480.

By the way, # cat /proc/sys/fs/file-max shows  26145349
This is holding up an application installation. Any advice appreciated.

Howdy, Stranger!
