[CentOS] Using a program

OS: CentOS 5 x86.


There is a program I am using which requires a start up service running. 
The service runs in Runlevels 3,4,5. When I am using the program as a 
root it works fine. When I am using it as a user it produces an error.

If I do as a root, /etc/init.d/program start, then I can use it as a 
simple user. I have emailed the company that makes it and had no 
response. Any idea on how to fix this?
