Depends on what system you're using. It'd have to be set somewhere in the boot process to be inherited by everything, there's usually some sort of system or place for that but the details can differ.

NAME
ncad_addr - name of the Solaris Network Cache and Accelerator (NCA) socket utility library SYNOPSIS
/usr/lib/ncad_addr.so DESCRIPTION
ncad_addr.so is the Solaris Network Cache and Accelerator (NCA) socket utility library. Use this library with a web server to avoid support for the PF_NCA family type socket. The web server can take advantage of NCA functionality. Interpose the ncad_addr interfaces before the interfaces in libsocket by setting the environment variable LD_PRELOAD to ncad_addr.so so that it is preloaded before libsocket.so.1. The ncad_addr.so interfaces will be interposed only if NCA is enabled. See ncakmod(1). EXAMPLES
Example 1: Interposing ncad_addr Using Bourne shell syntax as an example, set LD_PRELOAD as shown below to interpose the ncad_addr socket utility libary: LD_PRELOAD=/usr/lib/ncad_addr.so /usr/bin/httpd FILES
/usr/lib/ncad_addr.so ncad_addr socket utility library shared object ATTRIBUTES

nca(1), ncab2clf(1), ncakmod(1), socket(3SOCKET), nca.if(4), ncakmod.conf(4), attributes(5) NOTES
Only applications that use the NCA feature, for example, web servers, should interpose this library. SunOS 5.10 18 Feb 2003 ncad_addr(4)
