Yes; setuid programs will not search some random LD_LIBRARY_PATH for libraries for security reasons. Just think of someone setting LD_LIBRARY_PATH to include his home directory and putting his own libc.so there. Unlimited power if there is a dynamically linked setuid root binary on the system (and usually there are dozens).

You have to put your libclntsh.so in the restricted LD_LIBRARY_PATH or run your app as user oracle with su or sudo, say.
