[CentOS] Unable open raw socket in CentOS 5 - SE Linux and kernel capability interaction?

I am wondering what is the interaction between SE Linux and the kernel  
"capabilities" in CentOS 5.1? I'm trying to open a raw socket and keep  
getting permission denied errors. I've tried using the lcap library to  
find that CAP_SETPCAP appears to be off in the kernel. For compliance  
reasons, I don't want to turn this on. I've also tried a hand-crafted  
SE Linux module policy. I have verified that the test program runs in  
the correct SE Linux domain and it generates no audit errors, but it  
still fails to open the port with permission denied.

It appears that SE Linux is not preventing the socket being created  
(as evidenced by the lack of audit messages), so what am I missing? Do  
I still need to modify capabilities within the program, even if I'm  
using an SE Linux policy?

Thanks
S
