Looking at the code in libjna-java, it appears that it already supports
fallback to the system path.  If the caller is fixed to (properly) look
for libpam.so.0 instead of libpam.so, does that solve the issue?

This has nothing to do with multiarch.  the unversioned .so was *never*
in the runtime library package, and is not the filename that anything
should be referencing at runtime.

Title:
  JNI unable to find libpam.so

Bug description:
  I'm currently packaging Jenkins for Ubuntu; this application has
  native authentication integration through the use of PAM. This was
  working fine i.e. the java native interface dispatcher was able to
  find libpam.so in /lib and all was happy.

  I've just updated my test system and native authentication no longer
  works; the JNI dispatcher can't find the library.  I have done a bit
  of digging and it looks like libpam.so.* is installed to /lib/i386
  -linux-gnu instead of /lib (as on Maverick and possibly earlier Natty
  releases?).  This directory is not on the java.library.path by default
  which I suspect may be the issue (see below for default java library
  path):

  /usr/lib/jvm/java-6-openjdk/jre/lib/i386/client:/usr/lib/jvm/java-6-openjdk/jre/lib/i386:/usr/lib/jvm/java-6-openjdk/jre/../lib/i386:/usr/java/packages/lib/i386:/usr/lib/jni:/lib:/usr/lib

  So I'm not sure whether this is a bug in pam or openjdk but I guess it
  could be either.
