Unable to load libsctp.so for non root users

Question

I have a Linux application that uses the libsctp.so library. When I run it as root, it works fine.

But when I run it as a regular user, it gives the following error:

when loading shared libraries: libsctp.so.1: cannot open shared objects file: no such file or directory

But when I do ldd as a regular user, he can see the library:

[sanjeev @ devtest6 src] $ ldd myapp

  ...
   ...
  libsctp.so.1 => /usr/local/lib/libsctp.so.1 (0x00d17000)

[sanjeev @ devtest6 src] $ ls -lL / usr / local / lib / libsctp.so.1

-rwxrwxrwx 1 root root 27430 2009-06-29 11: 26 / usr / local / lib / libsctp.so.1

[sanjeev @ devtest6 src] $

What could be wrong? How can ldd find libsctp.so, but when starting the application it cannot find the same library?

EDIT: , , setuid myapp.
